Ditto to what Anna said.
I feel for you and I feel for her. I believe that she may not be ready, but more importantly YOU may not be ready to listen to the wisdom and advice being offered here.
If you truly care for her, you must stop trying to control her and her drinking. She won't stop for you. Trust me. I almost lost everything, including my husband and I didn't stop until I was ready. You cannot control this, as badly as I know you want to.
Good luck to you.
