His sponsor is telling us "we should be living together to work thru this" and that as long as he begins his steps again... everything is going to be ok.
Did you hear his "sponsor" say that, or did he just say his "sponsor" said that? Sorry, but I have a VERY difficult time believing a real AA sponsor would say those words. If he really did, then he either doesn't know the true story or he isn't much of a sponsor. A sponsor's job is to try to keep his sponsee sober, not micromanage his love life. This all just sounds like a huge con job to me.
