It sounds like you are on your way to recovery! And your kids are, too! I know the lonely feeling very well. But, as someone once told me you really are not alone it's you and your Higher Power. So, lately I have been just talking to my HP and the lonely feeling seems to fade a bit.
Your husband is scared. Scared that you are getting help. They sometimes think that all Al-Anon does is tell you to get a divorce. They don't understand.
My thoughts are with you. Keep feeling that HOPE today! Use it as a lifesaver!
