Hi Bill,
Welcome to SR. It is an amazing and supportive community, and we are all glad you are here.
You have already received wonderful advice so I'm just going to reiterate the most important thing everyone else already said: please do not, under any circumstances, have children with an active alcoholic. You will sentence them and yourself to a life of literal hell.
Unfortunately you are in an extremely difficult and serious position. The positive part of it is that you get to work on yourself now, and through that work you will become a stronger and wiser person. This strength and wisdom will support you through rough times for the rest of your life. So this really is a powerful opportunity for growth for you, and for your wife as well, if she chooses it.
Again, welcome!
