Only with hindsight do I now think that my exP was probably EA in his previous relationship (with his ex-wife). Prior to that I don't know, as they all left him.
When we first got together he told me he had very low self-esteem and so I guess a lot of how he behaved towards me was symptomatic of that. I often thought he was jealous of me: my close relationship with my family, my friendships, my level of education, my total lack of ties (whether financial or family), my opportunities in the future. So he made me feel shit about all of those, but in little ways that niggled but I couldn't put my finger on why.
His relationship with his ex-wife sounded pretty grim, for many reasons, but I wonder how much of her behaviour came from him being a total prick at times. He told me she was physically abusive towards him and attacked him several times, that she's bipolar and so on. He never had any counselling after their marriage broke down and he still has lots of issues from his childhood that he's never dealt with.
His trouble is that he doesn't think his behaviour is wrong. He came to pick up his stuff the other night and he turned it all on me and made out that he was the wronged party, refused to acknowledge that the things he'd done (he asked me to list them and I didn't see the point) had killed almost every bit of love I had for him.
I hope the next girl he meets sees him for what he is ASAP and tells him it's his problem, not hers. Maybe then the penny might drop and he might realise. But there's probably a greater chance of pigs flying by singing the theme from UNKLE.
