Please consider Al-Anon. You are not happy with the situation you have right now. Why put it off? Sure, it takes effort, dedication, and work, but Al-Anon can give you the support you need. It can also get your focus off your AH.
I mean, what are you gaining by remaining stuck or making a plan to have a plan? I lived with this for years. I was in desperate need of a program, just like my AH. He chose to drink himself into the grave. I chose to seek recovery.
It is your call, but if you stay you are going to continue feeling sad and ignored. Nothing changes if nothing changes.
