I stayed in my last relationship despite is being utterly toxic because of one reason only, I was madly and utterly in love with this woman. She had a lot of mental problems and daddy issues which I knew about up front but had this AMAZING energy which drew me to her. All of my friends warned me about her and her reputation. I clearly ignored them. A year and a half later we broke up. By the end of the breakup I've got major depression because this woman was everything to me and I never felt secure in the relationship (normally not my style) and wound up with crippling anxiety I took meds for. We stayed sort of friends for a while and she would message me every few months sort of leading me on. The final straw was she had a migraine one day and acted like an absolute jerk despite the fact I had just given her several hundred bucks to help her pay rent. I accused her of using me for money which she balked at and threw a huge fuss about. Several months pass by and I come across some messages between her and a friend. Apparently she was seeing two people during the time we dated and fucked two guys on the same day two weeks after we broke up. Oh and the argument she balked at? She admitted to her friend that she didn't break up with me that month because "I need his money this month". I'm still unsure if the entire relationship was a lie or what was truth. Thinking about it, I actually think she might be a sociopath. Total mind fuck.
