If she has no plan of staying, maybe she should stay gone out of the kids lives. I hate the thought of them losing her all over again each time she is motivated by guilt. Is it guilt that has kept her away or is it guilt that brings her back? Everything becomes complicated again. I think before she has a single thing to do with the kids ever again, I might demand on at least six months sobriety. The kids don't deserve to hear her version of what love is. She needs to do the work.
