I had this experience as well...my ex was brilliant at saying things that I to this day cannot get out of my head. A lot of those things made no sense in relation to me and that's why they bug me so much...one of the things my ex called me after *he* canceled a trip at the last minute that *I* paid for, was a brat. I was already crying, already sad, and that's all I was to him. He then proceeded to tell me he was interested in someone else. Who's the brat?
So a few months ago I was out with another male friend and he asked me about how I managed to support myself all of these years and whether I ever asked my parents for money. The fact is I haven't, and I'm far from a brat, I work very hard for the small things I have (not much). He told me he thought that was amazing and really admirable. It was the antidote.
