+1 on what Anvil said.
Confused, sorry for what you are going through - big hug to you.
Of course she blames you (that's what alcoholics do), and of course you feel guilty as you were "abandoning" a person with a disease. Your only role in her alcoholism is that you have been putting up with it for so long - and sounds like you are addressing that.
You are doing the right thing for your kids - she is dangerous to have around. I ended up getting supervised visitation and drug/alcohol testing for my son's father - I can never be too sure anymore.
Good luck with everything and keep us posted!
