It is a common tactic of alcoholics to point the finger of blame everywhere except at themselves. Ridiculously common, in fact.
You have the right to build your own life free of this kind of abuse. Your children have the right to a healthy family life, so they don't model your husband's behavior when THEY have families (which, unfortunately, many kids do) He treats you this way because you accept it.
Consider finding an Al-Anon group near you, or maybe even some personal counseling, to help find your way through this to a healthier life for you & your kids. That was a way that I started to create a plan to gain personal power and control over my own life. Good luck, and keep the faith. You can have a better life if you're willing to put the energy and creativity into creating it -- I did, and I'm no superwoman
