Wow AP. I know you're here to get some things off your chest and I can see that this guy has caused you some pain. But I have to ask the obvious, what about you and your newborn?
Being an addict/alcoholic I can tell you that what he's doing is going to come first before anything else, unfortunately. I wish you the best and hope that you'll put yourself and your new child before him and his issues.
Welcome to SR!! You'll find a lot of great support here. :ghug3
