If you must be in contact with him because you have a child together, then let that be it. No discussions of anything other than as they involve your daughter. If he moves on to other subjects, you can say you need to hang up. There is no need to talk to him every day. If you are positive that there is no way he will "get his family back together," then you need to tell him that. He shouldn't have any false hopes in that area and if he drinks because of it, it is NOT your fault. He's a grown man and you cannot MAKE him do anything. Continuing to converse with him and be involved in his recovery is sending him mixed signals and, as said before, you need to decide what you really want and then act accordingly.
