Thank you, Job. Makes a lot of sense what you are saying. I do wish I knew about DB site 2 years ago. I will do as you suggest. It's not easy but after our last fight I'm determined not to let him trick me into "us" talk again. It will be easier now as I don't insist anymore that he spends more time with the kids. Even when he was with them he was in his world and didn't really interact much so it's better this way.
I do hope he gets better, it's really difficult to watch his self-destruction but I do know that I cannot help him. He uses whatever I say against me and can be really cruel. Then he sends an e-mail to apologise, says he shouldn't have said what he said. I did not reply to the last one & not going to. It feels like he wants these fights but blames them on me and says he cannot stand them. It's unbelievable how so intelligent person and so reasonable and realistic at work context can be so lost in his emotional life. He has the same issues with his parents and the kids but I am the only one he can cut out of his life & that's what he's trying to do. Patience is not my strong point but it seems I have no other choice... I just hope he won't rush to make his AP pregnant just to "win" over me.
