Hi Megan:
I am sorry you are struggling. There is no excuse for the way he is acting, but if you continue to accept the apologies there will be no change. You have alcoholism in your family, so you may have grow used to this chaos. There is a better life out there for you, and peace.
Also, we teach our children how to have adult relationships by watching us, and I'm sure you don't want your daughter to learn that getting drunk and abusing a loved one is acceptable.
We teach others how to treat us, and I am afraid you have taught him it is ok to behave like this, I am sure this was not your intent.
It is no way your fault, and you can't make someone drink, but you can make a decision today to not allow yourself to be treated like this any more.
