Take care of yourself and your daughter first- if you can do anything for him that has to be a distance second place priority. Look for any resources that are available to you locally, too. There are usually many programs that can help emotionally and economically.
I would suggest you look into Al-Anon, Sparks. You've gone through a lot already and it has to be tough for you. At Al-Anon you'll meet people who've walked the road you're on and can help. Of course, SR is a great resource as well.
Don't feel guilty about this! You husband is an adult and responsible for his own actions. He will have to live with the consequences of his actions, you need to do what's best for you and your family.
