What do I do?? Who is better for me...?

i am 17, my bf is 19 and his friend is 21. (in the present, it starts when i was 15, my bf was 17, and his friend was 19) i have been with a guy for 2 years now (in 3 days to be exact) and when i first met him, i also met his best friend who is a bit older than he is. my bf 'saved' me from an abusive person who i wasnt exactly dating, and i was really thankful for it, and i really liked him. after a few days of hanging out with me, he asked me out, and his friend who was sitting close by looked kind of upset... but at the time i didnt think anything of it. so me and my bf were going out, and his friend stayed out of it for the most part, till about 3-4 months later when he was really drunk... when i was about to go to bed, and my bf wasnt there, he got a bit touchy... and i just sat there frozen, not knowing what to do. At All. i told my bf about that after... and he got VERY pissed off and threatened to call the cops on him, and said he is a rapist..... but i didnt see it that way... after that i was added on facebook by his friend and he apologized after that happened, his friend kept telling my bf he would fight him for me, wouldnt leave it alone... my bf forced his friend to block me and him on facebook (without me knowing.) so i assumed his friend hated me... i slowly forgot about it tho, so i didnt expect anything else to happen. now, last yr, just a few weeks after mine and my bfs 1 yr, he broke up with me, and called me names, like slut, idiot, cunt, and said to leave him alone... but i was an idiot and i didnt. i tried for a month and a half to get back with him, and eventually he gave in.. and we stayed together till now, but he planned on moving away without me.. (but he didnt) and he bitched at me DAILY for the stupidest things, and he still does. daily. closer to the present now, 4 months ago, his old friend came back into our lives. ( i will call him my friend now.) he stayed with us because his mom kicked him out, and my bfs mom said he could stay with at our house. for his entire stay, they treated him like shit, stole his stuff, called him a pedo and a rapist, and accused him of looking up a 15 yr old girl. the entire time, my bf wouldnt leave my side. my friend couldnt take it anymore so he moved out, forgetting a few things, and some of his things were stolen. i didnt know what to do, so i just stayed out of all of it. till about a few weeks ago. since he added me on his ps3 while he was at my bfs house. i msged him on psn and asked if he wanted me to return his things to him... he said "yes plz" so i said i will find a way. after that we talked for hours on end, and eventually he re added me on facebook, and then on skype. and we talked for about 5 hours, almost all night. he told me he could see that my current relationship is a bit abusive, and it isnt healthy for me.. i agreed cuz i honestly felt that too.. and my mom hated my bf, and so did the rest of my family. my bfs family doesnt like me much either. he said he rlly liked me.. and asked if i could give him a chance, and that he wouldnt be anything like that.. i ended up going to his house a few days later, without my bf knowing, cuz i know he would freak out. and we hung out... i was terribly shy at first, cuz i wasnt use to it.. but he helped me calm down, and we had a good time :3 he was rlly nice, and he made me feel really happy, and even loved.. i stayed there for 2-3 days, and we watched a few movies, and ended up cuddling.. the second night he had a bad nightmare, and was whimpering in his sleep, so i woke him up, with the help of his therapy dog. lol.. and he cried on my shoulder and told me about a traumatizing past relationship he was in... and said it haunted him like crazy.... i comforted him and said i would be there for him.... and we cuddled till he felt better... when i went home.. all i could think and care about was him... my bf just seemed mean and annoying after that... and too bitchy and clingy... i really do want to give my friend a chance, because i know he isnt as bad as people think he is, but i dont want to just leave a long relationship.. it would really hurt my bf.. but my friend just seems more... right.. for some reason.. and i really really dont know what to do... any ideas.. it is not important at all, but my friend is a lot better looking than my bf as well.. lol.. :/ im a bit scared to post this..

I think you know what to do, but your just scared to admit it. Leaving a long relationship like you and your current boyfriends is hard, but honey, you can be with someone for 2 years and feel nothing. And you can also be with someone for 2 days, and feel everything. I guess what I'm trying to say is, do what you want. Not what you think u want. There's a whole new world waiting for you with this "friend" of yours. Go for it. Your still so young. Live it up. Because you don't want to spend your life wondering what could have been.

ty.... :'3

I think you need to start with ending your current relationship before you think of doing anything else. If you are starting to develop feelings for someone else it is unfair to continue your current relationship. And even if you are better off with the friend you have to understand what dating him would do to the friendship of him and your boyfriend. Often the most difficult path is the one you should take. I recommend ending things with your boyfriend and waiting before you make a move on the friend. That way you know your feelings are genuine and not just based off of tabooness.
