<human>: Can you summarize the given text in a few sentences?

This happened about 5 weeks ago during finals week in college. 

I got done with my final I had that day and went to see my girlfriend at the time. We ended up in my room where she took a nap. I started looking over some stuff for a final I had later in the week. I had a feeling stuff wasn't right because she went home the weekend before finals to study which was kinda strange and she didn't seem herself. So while she was sleeping she got a message from a guy she is really good friends with back home. He has a girlfriend and I was never told this so I was worried that she was talking to him and cheating on me. I saw a message from him and opened it.  The last message she sent was, " I decided to break up with ryraibs47." I then went through messages to her best friend in college and she was talking about it with her too and how she wanted to be single and be best friends with one of my good friends at college. I freaked out and stormed out of my room which woke her up. I came back in and I was a little emotional but we decided to take a break and we would talk in a week. That turned into 4 weeks. We finally talk and she says she was going just talk to me before we left college and just agree not to be with each other so much because we spent all day everyday together for like two weeks. I was planning on talking to her too because it was way too much. She also didn't tell me we didn't like things I was doing which I thought were perfectly fine because she always seemed happy with them. But she said since I went through her phone she felt like her privacy was invaded and that I was too over protective while I just a didn't want to get cheated on. I didn't want to go through her phone, I just felt like something was wrong and there was. We could still be together but since I went through her phone she doesn't want to try and make it work. So reddit TIFU by going through my ex-gf's phone and ending our relationship.
<bot>: Went through ex-gf's phone cause I thought I was being cheated on. Didn't want to but was curious. Could still be together if I didn't cause the guy has a gf already.
