Dear OP,
So sorry your DP is behaving so horribly to you. I know you are not at the stage where you would consider ending your marriage, so people piling in with 'Leave The Bastard' sentiments does not fit with the stage you are at. I suppose all those people for whom 'this was me five years ago', were also all once at the stage you are at now i.e. saying 'he may be depressed or he has had a hard time and that's why he's being so nasty to me'.
You are trying desperately to find a solution - you are determined to build a happy home for your babies and to fix it - AND you think it must be up to you to find it. This is exactly how I felt. I thought determination and grit would get me through the 'rough patch'. I felt I just had to think really hard, find some reason for his abominable behaviour and tackle the reason. Depression seems an obvious choice as a reason, and I often felt that might be at the root of things with my STBXH.
You absolutely do not want to be told you were in an abusive relationship. It is horrifying. When I was told - by the Relate counsellor I had dragged H to - I was shocked and almost offended. 'What me?', I thought.
Nobody wants their marriage to fail. As it does feel like failure. I expect everybody on this thread who had to leave an abusive relationship 'really, really' tried to save it for all they were worth. The sad thing is, I realised that the only way to stop my STBXH being vicious, angry and controlling to me was for us to split up. I tried everything I could think of. In the end, you realise that he is not vicious, controlling and abusive to other people or work colleagues - no, it is just for you and a smattering for the DCs as well. I loved him, but he drained the love out of me just as surely as if I had been an innocent veal calf hung up and bled dry. I found my strength on behalf of my children eventually and kicked him out. He is still angry, vicious and controlling but I do not live with it. That was the only way. But I only got there after eliminating every other possible thing I could think of. That is probably where you are now and I really feel for you. Not in a patronising way, just feel the pain and confusion that you are in. You will be confused...it is hugely confusing to be treated like this by someone you love and who is supposed to love you. It just does not add up.
The posters on here are supportive. It may not feel like it, and maybe some have been pretty brutal, but belive me, we are watching your back and we have read the script a few pages ahead of you. It's a horrible thing to come to terms with, but your OP was pretty horrifying, even if you actually didn't realise the picture you were painting.
Good luck with everything and be brave. He seems like a man who is happy to poison the atmostphere of his home, abuse his wife and children and blame them for his misery. I don't have much time for someone like that. How dare he treat you like that. How dare he?
