KidsR#1....It sounds to me that his goal is to get back into the house---to return to the former status quo. What was the understanding between you two when you separated?
Did you formulate any boundaries for yourself?
Your post doesn't give any information about his sobriety or whether he is actually working a program.
Be careful of listening to what he says that AA members have said about your relationship---alcoholics are known to put quite a spin on what other people supposedly say.
You do sound very uncertain as to what you want and where your boundaries are except for staying in the relationship. Maybe that is where you should focus more of your efforts---on yourself....as to how you feel and what you want and need.
Just some of my impressions as I was reading your post.....
