You are right, though, it's nobodies business but my own. My ex-fiancee understood though, when I told him. From his point of view though, he knew exactly what damage my mother had wrecked upon me, and knew it was really only a matter of time.
It would never come up in normal convo, except that people are curious as to why I'm living in OZ, as a kiwi. And with no family. (Yes, moving countries was the only way I could see breaking contact was possible.) I guess it's kinda rare for a women not to be close to her mother. I wouldn't have thought so though.
