Welcome,
I'm sorry for your situation.
If you want a divorce, it's probably a good idea to speak with the marriage counsellor about your feelings. Also, you might want to speak with an attorney and get an idea about what rights you would have and how to go about it.
I would also suggest that you check out AlAnon in your area which would be a support for you.
Hopefully your husband will make the choice to seek support for himself.
