You're right, your son and wife don't deserve an actively drinking alcoholic father and husband.
It's up to you. You've got one of the best reasons I can think of to stop drinking.
You also have to do it for yourself. It's your life and you are responsible for yourself first and fore most.
I don't think of quitting forever. I've got four years sober and I still can't handle forever.
I'm going to try and not drink today. I was a bad alcoholic, so there are no guaranties. I have no control once I start drinking, but if I don't take the first one I won't get drunk.
Your family needs the sober you. They deserve, and so do you.
Stop the binge and realize how much you have to lose, and take my word for it, if you keep drinking you could lose it all. I did.
I wish you the best, and remember, you don't have to drink today. One day at a time.
