They went out for 8 months last year. He mentions her a lot. She just seems to pop up in conversations every now and then. He says he can't stand her, that she was crazy, had mental health problems, was stupid/thick (despite having a PhD and holding an academic position at a local university), that she was rude to his friends, that she was vain/shallow (only cared about designer goods). He said that she never meant anything to him (despite being his longest relationship in 15 years - he said that his previous relationships only last on average a couple of months). I know that he had introduced her to his elderly parents and had gone on several holidays with her including a holiday with a friend's family.
I asked him what it was that he saw in her then and he said that it was all about sex - that she was "very wild" and that he didn't want to go into details.
It makes me think that he still has feelings for her and also screams alarm bells in that he doesn't seem to have anything nice to say about her. I don't really like any thing that he is saying tbh.
What do others think?
