Long distance friendship

So I've been talking to this girl that I met through social media for about 16-17 months now and about 7 months after talking to her I told her that I really liked her but she didn't feel the same way and usually if I liked someone and they didn't like me back I wouldn't speak to after a few days/weeks it would just fizzle out and become awkward but this is different I'm not sure if i just can't get over her but she severely affects my mood and I don't think she realizes it, I try my best to not show it though and she tells me "everything" she's told me I helped her a lot, I would always keep her company when she was going through family issues but every time i would ask her to voice chat she always declines even when she's happy though she sends me snapchats and i can hear her voice and see her and i have enough proof that she's real before anyone might assume she's a fake or something, anyway so i thought i'd ask her about it but i might have come across mad about it and at first she took it as a joke but then when she realized i was serious she pretty much sent one reply then ignored me for a day so i messaged her again asking if she;s even going to say anything about it then she said she's awkward and didn't think it was a big deal and that was a few weeks ago even though we play some games together she still hasn't made any effort in that sense knowing it bothered me, it wouldn't bother me as much but i know she voice chatted with other people before. people who have deleted her now and that she hasn't known for half as long as I've known her this really tilts me for some reason it just makes me think that there's something wrong with me, I would feel awkward asking her again i don't want to come across as annoying especially because I talk to her in text everyday literally message none stop most days and sometimes I feel like she doesn't care about anything but me listening to her and she knows i would never delete her so I'm not sure if she's taking advantage of the way I feel about her or something, I feel like i maybe rely on her too much sometimes for company, I'm aware I'm a pretty high maintenance person when it comes to friendship and I hate it when people don't give me a 100% of their attention, but in this situation I feel like I've really tried my best in order to stop that part of me and she wont even talk to me even if we're doing something online together like playing a game or watching a stream or something I don't feel like it's that much to ask sure it might be awkward at first but I'm sure we could build it up to be just like it is in text but she won't give it a chance so idk what to do I dont want to stop talking to her but this really bothers me.

You said: I'm aware I'm a pretty high maintenance person when it comes to friendship and I hate it when people don't give me a 100% of their attention... She's just not that into you. Honestly... I don't blame her.
