My last relationship was 12 years long. Dunno why I let it last that long as she was very emotionally abusive and unstable. It feels weird looking back that I allowed someone to treat me like that, I have a really healthy relationship now thankfully.
Obviously it ended badly. Well actually it ended better than the last 5 years of being in it were. I caught her telling my really good friend (our mutual friend) that she had feelings for him (obviously he told me right away, not sure why she thought he wouldn't but she was pretty crazy), and it broke the spell. She lost her power over me and realized it and has been really nice in the separation, she didn't try to get anything from me in the divorce and she's never been abusive towards me since then. We have no contact anymore. Over time I have become disgusted with the whole thing and although she hoped we'd remain friends, and when we separated I felt surprisingly positive towards her, over time I realized I wanted her totally out of my life. When I told her it was over and why, I think she finally realized how terrible she was to me. She isn't a bad person, she is just really damaged and refuses to admit she has a personality disorder. I think she's really sad about it and might still wish we were together based on some conversations we had 2 years or so ago, but she knows there is no chance of that. I do feel kind of bad for her even now, but I'm so glad to have escaped. She lives with her mom because now that I'm not supporting her, she is basically unable to support herself which was also true during our 6 years of marriage. She realized what she had too late. I get a bit of satisfaction from that but mostly I feel sorry for her because she really is quite mentally ill.
