Your husband chose to be with you but he chose to give his daughter life and owes her much more IMHO. I told my husband that is he ever made my son feel unloved or unwelcome in my home he could find another roof to sleep under. My son did not choose to live and I will care for him as long as necessary for him to launch independently. Some birds fly when kicked out of the nest and others drop to their death. I'm not playing Russian Roulette with my sons life and anyone who tries to insist I do, better get out of my way.

Do you have any kind of pleasant relationship with your step daughter ? Does she value you as a person md consider you someone to trust who she can confide in? What kind of relationship are you willing to have with her? It should be up to you and your husband on if she comes to live with you both. Not just you and not just him....all 3 of you have a say. If my sons ever need a place to stay though, my husband knows they have my blessing to stay with me and he will not impede my relationship with my children if he knows what's best for us all.
