cag,
Welcome to SR!
I also strongly recommend AlAnon, shop around-find a group that feels comfortable to you and give it a try for 6 weeks - something you can do for you.
I'm sorry for what has brought you here. Please know that by asking your husband to leave, you were doing what you felt was right at the time and you have seen positive results since. Do not accept guilt or negativity from anyone outside of your home and immediate family - they do not live your life.
Others will be along w/more experience, strength and hope soon. Welcome!
