Vague responses from girlfriend and feeling worthless

Hello there community, let me start all the way from the top, so me and my girlfriend have been dating for 10 months but for the last 2 months it's been hectic. When we first started dating, things were perfect i felt like she really was the one for me and even if we went to different school, i got to see her every so often. Things were good until around 7 months into the relationship we would get into arguements for the stupidist things, me myself, i don't really like to speak my mind because if i do, she'll take it the wrong way like she does everything and i word things i want to say to her in a way tht would prevent an uproar but we end up arguing anyways. So this went on for about 2 months or so on and off and at around 9 months i asked her if she could give me another chance and i made her a email the night before to patch things up and things were alright but i began to notice that everytime we make up after a fight, she would be very vague with most of her texts responses being 'yea' when i would ask her if she's ok when she's clearly still mad at me so before the summer things we're alright and sometimes we'll have a full conversation over texts and over the phone or sometimes she'll respond vaguely and it'll be hard to reply when she texts like that, but being the humble guy i am, i didn't say anything and kept going with the flow. So as summer kicked in, i've been trying all i can to make things the way they were just like we first started dating and i didn't ask her much if wanted to talk on the phone but i was trying to patch things up and stay focus on making her happy and sacrificing everything else. So around the second week of June on a Friday, she's about to go on vacation for a week and the day goes by normally until she flips and says that i don't love her or feel the same about her because i didn't ask her if we could talk on the phone or video chat before she left for a week and i told her that i've been so caught up in trying make her happy that it slipped my mind to ask to call her. But i talk on the phone with her a few days ago in the morning and any other time she said she couldn't, but i definitely should of asked to call more often which was a mistake on my part. And she asked me if i felt the same about her and i was honest with her and say i don't but i still love but i was scared to tell her why because of how she'd react to it and take it the wrong way and kept it so myself. So i just said that and she was pissed at me and said that i could be a single man for the week that she was away and talk to other girls if i wanted and to just give us sometime to think. So for the whole week, i kept my mind on her and was thinking of every way i could be a better guy, and while on some days i just broke down and cried myself to sleep knowing that there's nothing i could do. On the day of our 9 month anniversary, i went out of my way and made her a nice slideshow describing her and what i would do to be a better boyfriend to her. So the rest of the days i kept thinking when she came back on that Sunday before it will be a full since she has left, i asked her how was the trip and did she enjoy it, we talk about it and she showed me some pictures from her vacation. I noticed that called me babe very rarely but i guess she was still mad at me so i asked if she wanted to talk about the whole mess we had and said 'no im still not in the mood for it,' so i left it alone and she had to go. So the next day, we had an alright conversation throughout the day and i guessed that she was feeling abit better, so i asked her if she wanted to talk about it and she said that she doesn't know if she could give me another chance and that she only sees me as a close friend, and i begged her if she would and she said fine, she can only be close friends with the 'new me' and could only be together if the 'old me' wants to come back. So i agreed to it and from there forward i've doing nearly everything i can when i went on vacation i bought her some things from there to give for her. Also when i came back (now in the first week of July) things were the same, she spoke very vaguely to me even over the phone, but i refused to give up on her so i made a booklet for her one night describing partially how i felt and adding alot of her favorite things and song lyrics in the booklet; it took me hours to make it and i was planning to show up at her house and surprise her with it. Things didn't really go as planned and i grew abit impatient and just told her about it with pictures of the booklet and briefly describing it. She seem everything but amused, she said it was good and nice of me but i felt it wasn't enough, so throughout the weeks i added more to it. Also, to do something with my time other than weep, i would find random songs and ask her if i could play them for her and she said 'it's fine, no worries' like i haven't spent hours trying to learn it. I felt like crap, but i kept kicking my way out of hell and stayed up on night trying to draw her. I thought i did a pretty good job and later on that night, i took a picture and sent it to her, she simply said it 'looked good' without any emotion or calling me babe. I just said thanks and we talked (her being vague again), and she had to go. So i further felt like it wasn't enough for the 'old me' to come back, so i furthermore made the picture look better for her and added alot of detail and a description with her name. I showed her and she said the same thing very sarcastic-like, and i didn't think she was at all amused, so i added more things to the booklet over the many days, to hopefully make her feel like i truely put my heart into it. One day she said she was going out with her family, so i was asking her what she was doing throughout the day with her family and i also asked her some other questions like her favorite flower and other things i could add the the booklet and in a sarcastic tone, she texted 'dude you should totally be a detective, because you are good at interrogating people' nothing could describe how infuriated i was, but i tried to keep a cool head and just simply apolgized for annoying her and more & more she started to be very vague. It is so hard to talk to her when i type a 2 paragraph text and she texts a mesily 2 word text in response, it drives me insane, but again, i was humble about it and never mentioned it to her yet. So days went by and the same vague attitude was with her on a nearly daily basis, she no longer calls me babe, and even though she says she still loves me a month ago, she shows little to no interest, so one night i was very depressed and carelessly posted on facebook that i felt worthless and that i can't fix anything. I was beginning to feel out of hope. My brother replied saying that she's the worthless one and im doing everything i can and his girlfriend liked his status and i disagreed with him and said i could do better for her. I'm not a guy to started drama on a social network but the next morning when she saw my post, she said 'so im the worthless one, tell your bro i said thanks' and there was another arguement and i kept telling her that in worthless for messing up countless times and being unable to fix it and just for being an asshole, but she didn't listen to a word i said and kept going back to the fact that my brother thinks she's worthless along with his gf and my whole family along with me is going to hate her, and i told her that's not the case and that my parents don't even know we're having problems so they wouldn't hate her for making me feel the way i do. And i kept saying everything i do for her is not enough and she just says that she doesn't know what to do anymore and doesn't know if she wants to just make this whole drama that started 2 months ago a thing of the past and it could be a big stepping stone in our relationship. And she strayed away from the conversation saying 'this is making me braindead let's talk about something else wyd?' and we had a regular vague conversation again and she had to go. For the next few days i didn't get to talk much to her because she was with family for the weekend, so i respected it and got through it. One the last days with her family, she went to the beach complained that morning that she felt very ill and had a very bad stomachache. Even though i couldn't be there for her physically, i was there for her through text and took care of her the best way i could by describing how to cure the stomachache. After texting about 2 pages long on how to get her better she said 'Kk' and later said she took some medicine, like i told her to, and she felt alittle better but she never thanked me, but i kept my cool and was grateful for her feeling better. She texted me later at night after she got back and said she threw up and felt horrible the rest of the day and i kept trying to help her but she shut me out and just said 'im fine' and we talked about her night, again her being very vague, and she had to go. The next day, she felt better as if nothing had happened, and i was happy so we went on through the day and i began to notice that everyday it seems like her care for me slowly slipped away even though i nearly went out of my way to make sure she's perfectly fine, it seems like she doesn't care, but i stay positive and didn't give up. A few days ago, my brother's girlfriend suggested that she would ask my girlfriend if she could go to the movies this weekend, but she doesn't know i'll be there so i could tell her face to face how i truely feel to clear up alot of confusion. She said that my gf is booked for the weekend and said that next weekend she'll be able to go. Also, the other day, my girlfriend was at band practice, and again at this point it was hard to talk to her because i would ask her a question to start a conversation and she would always answer 'Yea' and never ask me back. I just wanted to scream but again i kept my cool, and she was acting stranger than ever so i asked her countless times if she was alright and she snaps and says 'damn i had to tell you im alright 5 times' and i was pissed off but i kept my cool and apologized and afterwards she said 'Ok' to almost every conversation starter i said and later that day, she sent me a text with my name and a sad face after i asked her a random question because it seemed like anything else was invalid and i asked her what was wrong and she pushed it away and said 'forget it wyd?' and changed the subject was very gloomy and vague as always that night. Today was the sane old BS that had been going on with vague responses and today i went to a waterpark and wished she was there with me and she said sarcastically 'aww really' and i said yes honeslty yea, she said aww in the same tone. I felt like she gives to shits whatsoever and it takes me so long to think about what to text to her. Im all out if ideas, if she doesn't understand how im feeling when i tell her face to face next weekend, im going to give up because all the anger, sorrow, and depression will all release and idk what will happen, i really love this girl and i wish i was abit more careful not to screw things up, i hope she understands what i've holding back all this time. Sorry for the long post i really don't know who else to pour out to, what do you think i should do or what am i doing wrong? Thanks for any replies.

I don't think it's your fault to be real with you it seems like she maybe doesn't want to be with you but keeps dragging you along and you are letting her you deserve better than that
