<human>: So, this past Wednesday, I finally broke up with my girlfriend. In July, we mutually decided to break it off but it was more of a break than an actual breakup. A month later, we started talking again. I found out during the one month gap, she fucked two dudes. I decided that since we were not technically together, I can't put too much blame on her and with her consent we decided to revive our old fling. I still deeply cared for her and I thought she did the same too. I mean we had been together for almost 2 years and it was hard to completely get over my feelings. We both agreed that we would work on our relationships and I clearly mentioned to her that any sort of cheating would mean an end of us forever. Well, last weekend I was out of town and she fucked another dude. I only found out about it on Wednesday while she was sleeping on my bed while acting like nothing happened. I just couldn't hold my emotions and kicked her out in the middle of the night. She was saying that she wanted to talk and blah blah and how she was drunk but I was having none of it. Since that night, I have decided to completely cut off her from my life and deleted her from every social media that we were friends in. Its just that I am feeling really lonely and I really do miss her. I genuinely loved her. Right now, all I can think about is how she is getting on with another guy and I am here drinking by myself feeling pity on myself. I just wanted to know how long will this last. I feel like shit and I have been hammered drunk every night since that fateful night and can't focus on anything. How do I overcome this?

Can you condense the text into three sentences or less?
<bot>: Was trying to make it work with a girl I had been together for almost 2 years and she fucked another guy. Now, I feel like complete shit because I have realized we would never get back together.
