Thank you for your reply,Mike.
Suppose I put things a different way to her?Supose I tell her how much her behaviour upset and hurt me and how shocked I was by it bearing in mind our previous friendship.Suppose I say that since she always blamed her behaviour on illness,that I'm trying to understand that.If she responds badly/negatively then maybe I'll know that fundamentally she is the heartless person her behaviour suggested.On the other hand,if there was anything genuine in what she said about how much the friendship mean to her,then she'll respond positively,won't she?
One of her issues was with low self esteem and ,ironically,it seemed that because I did genuinely care for her,she couldn't cope with this-she once said that she was "too important" to me-anyone understand this? She seems,on the contrary to seek out relationships in which she knows she is destined to be hurt/let down sooner or later,but seems to prefer that.
Anyone help further with understanding ,or what I should do-I do feel the need to actually address this matter in some way,for my own sake.
