Hi and Welcome,
After reading your posts, I am very suspicious of your husband's behaviour. My advice is to distance yourself, as much as possible, from his strange behaviour. I think he is trying to control you, in some way. Try to focus on yourself and your recovery. You have decided that sobriety is right for you, and you can do it.
Of course it's hard having your son leave hom to go to school, but you can get through this period. If you have free time, why not try volunteering in your community. It will help you to feel good about yourself.
