I read on your page that your h is a drinker, have you tried alanon for you and the kids. I tried it and it was not for me but it might be a good thing for the kids and yourself. I was married to my alcoholic of 22 years but developed drinking problem about 5 years ago. I stayed, which was my choice, stbx went into AA back in late February and told me she was leaving after being sober for about 2 months. If your kids have seen their father drunk then their is a very good chance that they know why you want to leave. You have to do what is best for you and you kids. If he has no interest in sobering up and you can't take it any more then you need to get out. I was told that alcohol was more important then I was and I still stayed. This is the second time stbx has abandoned me and I am never ever going to let her do this to me again. I wish I had never taken her back. There you now know where I am coming from. I wish you only the best and I really hope it works out for you and your kids no matter what you decide to do.
