I haven't heard from my ex since we broke up a year ago but I did run into her ex-husband last month (same SCA principality, I was a Marshal for his Field at West Crown) and he thanked me for getting engaged to her as it finally got her off her ass to finalize their divorce. Shortly after he got engaged to a prettier, smarter, and nicer woman than our mutual ex.
While I currently an single I find I am happier not being in an abusive relationship. I don't know what she wanted but I turned out not to be it. I hold no animosity towards her but I do almost want to tell her current boyfriend to watch out & get himself checked.
Tis better to be alone and sane than not but in a crazed relationship.
