<human>: My girlfriend and I go to different schools. The last month has been up and down. I feel like the passion just dissipated. She would come visit me and I wouldn't get excited. I ended up cheating on her, and I regret it so much. I broke up with her the next day (it was so hard but I knew i had to do it) and told her everything. She's saying she can forgive me so we've considered getting back together. I wasn't planning on her forgiving me and I thought it would all be over. But when she said she could forgive me it made me start thinking about getting back together.

      We've been on a break for a few weeks, but got in an argument already. Her ex has been texting her now that he knows we broke up, and I got annoyed. Her texting the ex has been in item throughout our relationship and she did cheat on me with him at the very beginning of our relationship. She retaliated saying that I can't get mad for her talking to her ex because of what I did (she ignores him most of the time). I now feel like every time I complain about something she's going to hold what I did against me (my cheating event was worse than hers). I'm now contemplating whether getting back together is a good idea. I love her, but I do find myself dwelling on the past of our relationship. I always talk about how amazing things WERE, and I think I'm holding onto the past too much.

Can you give me a shortened version of the text?
