Yes, I seperated from my AH in May. We tried marraige councelling. He is in extreme denial about his drinking problem and thinks he can control it. He wont seek help. I wont take him back. It's been six months and nothing has changed on his half of the world. I have just filed for divorce. I was hoping that he would realize what his drinking has done to our relationship but no luck. With that being the case, I have to do what is right for me and my son.
I agree with HappySoul "it was harder on the children to have him in and out than to create a stable, healthy, safe environment in a one-parent home." That is why I refused to take him back as long as he was drinking and now enough is enough. The mental health of me and my son are so much more important to me than enabling his additiction.
The outcome of a seperation may not result in what you hope for. The alchol can have such a grip on them that they see reality in a much different way than you and I. Good luck in what you decide.
