Hi J.,
Although I can't offer you resources, I do want to offer you some comfort because all "moms" are in the same boat regardless of circumstances....that's what makes us women powerful. God would not have blessed us as women if he didn't think we could handle it: being loving when we are angry, being forgiving when we want to resent, being wrong when we know we're right.
You can never change a person, you can only change yourself and it sounds like you would do anything to shield your daughter from an unhealthy relationship. It sounds like your husband has unresolved issues and most likely the reason he drinks. As hard as it may sound, believe that he's doing the best he can do with what he knows becasue he's hurting too. Love him and forgive him as the person you know he is and not the person he's "being." Communicate with him from that frame of mind and you'll open the communications with him so that there more of a win-win for you, him and most importantly, your daughter. We women always take the high road becasue our commitment to our children is greater than any circumstance life gives us...and know, this will pass with time. Show your daughter what it is to be a strong powerful loving women who can rise above circumstances and find resolution. You can do it, it's just taking the first steps that seem difficult.
Virtual Hugs going your way.
