Did I do wrong?

[Orije]

Hello. Sorry if i write alot. Me and my girlfriend were dating for 5 months and when the school year started, her being a senior and me being a freshman in college, she wanted to be friends until about january because she takes really tough classes and is in alot of college programs so she has to do so many essays during a period of time. We both liked each other alot and becoming just friends for the time being was tough and even her mom wanted us to be a little distant so i wouldn't distract her. I know she was't using her school work to not date me because we would talk before or after she does her work and she has alot. We only get to talk for about 5-10 minutes a day and it is really tough on my part and i usually hear from her that she was hanging out with friends after school for an hour or 2 and the thing that was killing me was that I haven't seen her for a month and when we did hang out she always said she was sad cause she was sacraficing her time to do work to hang out with me. I don't like arguments but she always said how her time is too precious and that I'm a distraction because she wants to hang out with me and be with me but school work is cutting down her time. The past 2 weeks i noticed she would be on facebook and i would try to engage in convo and i would notice that she would read my message but not reply and it bothered me. I thought maybe she was busy but i noticed she would comment on photos and statuses and when i asked she would say she was busy. I tried to bring up my feelings of how i feel ignored and she is pushing me away but she replied by saying that im over thinking and that if i understand that she is busy with school work, why am i always stressing her out and trying to get her attention? I always believed it was my fault and im maybe being an attention whore. To end this, yesterday she asked me to help her study and so i went. There i noticed she did log on facebook and went to her messages in which i saw she was talking to other friends of hers. I was doing my work and trying not to bother her much and she sent me a message and i replied. i then saw that she read the message but didnt click on it letting me know that she saw it so then i got upset cause of the many times she was online and i sent a message with it not saying she saw it i actually thought she was busy. I went home and she apologized cause she noticed i was making her sad and she says i should forget about her because she wants to be more occupied on her school work than anything else. I told her lets give it some time and we can work it out, eventually in the day we got into a little arguement in which she said she can't handle this right now and that im stressing her and i havent heard or said a thing since then. I really do like her and i want to stay with her Im not sure what to do now and i need some advice! :c
