Hi starsnstripes
I too have been following this thread over the last couple of days.
I think the one thing you need to accept is that he is an alcoholic. He won't admit that at the moment of course. I would also say that he is an incredibly unhappy man - hence the constant anger. He directs the anger at you because you are an easy target. I am not excusing it in any way but he is unhappy and angry and taking it out on you and using alcohol as a crutch.
I think the only thing that may make him wake up and see what he is doing is a huge shock. That of you leaving and taking the children. He will become more angry of course. You cannot ask him for permission to leave or tell him you are leaving. As others have said you need to get yourself organised (I think by doing that you will feel more in control) and just go.
I know you are worried for the children. Ironically doing this may actually save their relationship with their father if it makes him see what he is doing. Trust me - the longer you stay the more damage you are doing to them. And yes I do mean YOU. You are telling them that it is alright to behave like he does.
I grew up with an angry frustrated father who drank too much. I know only too well the feeling of knowing what time he should be home and realising that he was obv in the pub again. The feeling of knots in my stomach wondering what mood he would be in. All the feelings that you have about your H coming home, I had about my father. And so did my younger sisters. And so do your children. My father was not nearly as bad as your H and we still all felt this way.
I know you don't feel that it is bad enough to warrant running to a refuge but the sheer fact of his unpredictability and volatility means that it is. Especially to protect the children. He is getting angrier and his behaviour will get worse. He will becomre more volatile and more angry. He will take that out on you because that is what he does. Your children will see and hear it all.
So. Get yourself organised.
Birth certificates - yours and the childrens.
Passports - yours and the childrens.
Marriage certificate.
As much cash as you can lay your hands on.
Photos.
TAKE THE LAPTOP. It is not his.
The above is all you really need.
Nice to have:
Favourite toys of the childrens,
Duvet covers and pillowcases of the children for familiarity if nec.
I know you say you have issues with anxiety and depression but they won't go away with how things are currently. They are caused by how things are.
You just need a few days of being really strong and then you will feel so much better.
You owe it to the children. And you owe it to you.
