Nana, I know you don't want to be unsupportive. You've been incredibly supportive to snow on this thread
I'm just going through a similar thing to snow at the moment. My H is not an alcoholic but he is emotionally abusive with MH problems. He was doing really well up until 3 weeks ago, when he went back on the conditions that he was allowed to stay here.
He is moving out tomorrow - for the sake of the DCs more than anything.
My point is that although I know I am not responsible for his behaviour, I am in a constant battle with myself not to blame myself. It's very difficult not to make excuses for them and pretend that the DCs would be better off with their dad around.
I know that you all know this. But when you're in it, it is so easy to blame yourself.
There are two issues here snow. The first is that this situation is not of your making. You are not to blame for the pain that you and your DCs are in. You are the victims and you must NOT give in to that nagging voice that says, "Maybe I'm overreacting" no matter how tempting it is.
The second is that you ARE responsible for the welfare of your children. Having recognised the threat you ARE responsible for protecting them from it.
It's not fair that you have been put in this position - it's not fair that I've been put in this position - but we have to do what is right by those we love. This is the hand we were dealt.
So H goes tomorrow and who knows what the future will bring. No matter what I will know that I have done my best by my family.
Sorry for the ramble about my life.
I hope you find the strength. I know how hard it is.
