We've been together for about two years now and everything was perfect and going good, except for the fact that we are both going to college in a few weeks (we'll be 5 hours away) but we weren't worried and were just gonna let our relationship run it's natural course and if it was too much work then we wouldn't worry about it and remain friends. Instead about two weeks before I leave, she goes on a week long vacation with her family and while she is gone slowly stops talking to me for no apparent reason, I begin to freak out naturally. She comes back and says that she feels that this is the easiest way to do things (ignoring me and acting like I don't exist). So it literally went from us being head over heels in love, everything perfect and happy, to her acting like I don't exist less than a week later. 

A little bit of time has gone by, about 2 weeks, and there has been minimal contact but when I do talk to her I can tell she feels bad about something. Well I found out today from both deductive reasoning and finally taking my head out of my ass, that she cheated on me with one of her brothers friends on vacation. This was confirmed by her best friend and one of my best friends as well who didn't want to tell me herself but wanted my SO to tell me. She also tells me that she had no plans of ever telling me (she thought it was best I didn't know), and right after I found out, I called her and told her I never wanted to speak to her again and that she is the shittiest person I've ever met then hung up, she hasn't said anything yet.

I don't know what to do, I'm so utterly mad at her but there is still part of me that's crushed and sad and still loves her. Did I make a mistake by reacting the way I did? Is there anything I should do to talk to her again? Should I stick with my gut and not bother with her ever again? I have no clue what to do and would really appreciate some advice reddit.

SO cheated on me on vacation before college and and instead of telling me, made an excuse about how she didn't think our relationship could last and I found out and flipped out.

My SO asks for 2 weeks of vacation, I travel with her, she ends the relationship because she thinks it's easier to do so, I find out later that she cheated on me with her brother and, after a week of no contact,
