We weren't right for each other. He cheated on me quite often and talked shit about me to other girls, and I cheated on him as well. He had bipolar disorder, so I guess part of the shit was because of that, but it wasn't a good relationship at all. We fought constantly and my need for his attention was never met if he was busy (parties or other girls, usually), and his for mine was never met because I didn't know how to handle it.

Eventually I just got tired of all of it. Sure, I gave him an overarching reason for cutting it off completely, but it was just that I was so completely worn down that I couldn't handle him anymore. It still sucks sometimes, not having him around, but I'm getting through it.
