An alcoholic who cannot stop drinking and is not in recovery for life will never be or become a good responsibile parent...you are playing lets pretend, might be time to get real.
It would be very irresponsible to bring a child into the world with him. I know, I lived in the home of an alcoholic and I would not wish that dysfunction and abuse on anyone, let alone an innocent child.
Might be time for you to get yourself into therapy so that you can sort this all out, sounds like you are just spinning your wheels.
