I'm sorry it's come to this StrongEnuf, but if your AH is drinking again, it is your responsibility to get him to leave the home. Your children need you to advocate for them. They need you to choose them over him.
I think that if you go the social worker and ask them to tell you HOW to remove him from the home or how to begin divorce proceedings, they will help you. Do you own this home? Are you on the mortgage? I assume you are because you are the breadwinner in the family...The social worker can get you the legal help you need to kick him out. I know other SR members have done it before, so it *can* be done.
to you. I know this is a scary road to travel. But you are not alone.
