Thanks all.
To give a bit more background, she has tried meds but one made her suicidal and the other just made her really tired and even more grouchy. She has been to counselling and currently going through CBT. She will not go to marriage counselling.
She has her issues - her mum is a middle class alcoholic and her dad has had nothing to do with her since she was 17 (never met her dad but I know he only speaks with one of his 6 children so it isn't just her). She has low self esteem and knows this - no confidence etc. I have tried to support her through this for years and fully understand why the past has influenced the way she is. However, this gives her no right to behave the she does.
I completely understand why she feels the way she does about herself. I understand why this makes her treat me the way she does. It isn't rocket science. The irony is that understnading this and actually trying to be a nice guy and help her through it just makes it worse.
Bubblegum - appreciate what you are saying but in this case she has said I give her too much attention and it is suffocating. Given she has given me no attention for years and never said anything nice about me for years this is a bit rich.
"you can still be a part of your children's lives". I know you don't mean to but this bit annoyed me a bit. There is still this expectation that the Dad is a 'part' player in children's lives and mum is most important. As I said, I provide at least the same amount of time (and I suspect substantially more) looking after the children then she does. I don't want to be 'part' of their lives. I have a right to be integral to it whilst they are children which to me means being there for them all the time - not 3 or 4 days a week. I also could not help thinking that your first line 'if everything you say is true' really means 'well, there are two sides and if we heard his wife she would say differently'. This annoys the hell out of me. Would you think the same if it was her telling the same story? Would you be telling her that she can still be part of their lives? No, you would be telling her to kick me out no doubt for being a jealous controlling misogynist. Sorry, I know that you meant well but women can be as selfish and manipulative as men can be and sometimes it is entirely one person's fault in a relationship. I have tried really hard to find out what I can do to change. My wife says nothing. She says there is nothing I have done.
I have been to counselling myself. The counsellor advised me to get legal advice (I know this was inappropriate of her but still). Now maybe I am a good lier and could fool the counsellor but honestly I have agonised over what I have done wrong and other than care too much and try to help I can see nothing.
Anyway, sorry bubblegum. I know you mean well. Just all the things you are saying that she may feel - unwanted, unattractive etc. is exactly how she has made me feel for years and even though I talked to her about this she never did anything (apart from try to start an affair twice).
