<human>: So my gf and I have been together off and on for about 14 months now. The first ten months were great but then she went away to college and long distance has been killing us. We went on a two month break and in that time she had sex with six other guys. I didn't blame her for that, we were on a break. But she got very upset that I didn't respond to her texts when we were on break.
So, when she came back home after our break we decided to try and get back together and for a while it seemed to be working. I was happy talking to her every night and took care of her when she was feeling down and everything seemed to be going ok.
However, this weekend I got upset for a bit and asked her to help me as I had helped her and she simply refused. She told me to stop complaining and "man up." This was saturday night when she was going out with her sorority.
Sunday morning rolls around and she wants to talk and be loving again and I couldn't take it. So I told her everything I had been feeling. I told her I was hurt by how she treated me and that I can't handle feeling like we are only in a relationship on the weekdays and now she's angry with me. I really don't know if telling her how I feel was the right decision. I don't want to lose this girl.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Gf slept around when we were on break, hard to trust her in long distance relationship especially since her attitude towards me changes on weekends. Told her that, she's pissed. Don't know what to do.
