I have been in a place very similar to the one you describe and I'll tell you my experience with it. I chose to stay with him and believe him and try to help him each and every time he relapsed and went through treatment or detox. I was simply too frightened to leave (for his sake and for mine). I thought my boys needed to be raised in a home with 2 parents ~ and they were ~ except I was doing the job of both parents. I became "supermom" and did everything within my power to raise my children in a healthy home. My husband continued to drink and get sicker and sicker. To make a long story (22 years!) short... I believe it would have been much, much healthier to have ended this marriage many years ago. There is never a "good time" to do this... there is never enough money or the holidays are coming, etc. I look back with regret for all the time I lost. We are still married, but he is currently in jail. Great role model, huh? I know this is a tough decision to make! Hugs to you.
