I know I shouldn't do this but I'm strongly considering giving him an ultimatum....go to AA or we will have to continue on with our journey at a distance. Which greatly changes things.
If you don't want to be with an alcoholic, you should tell him this.
I suspect there is a genetic link for addiction. Addiction can also be a learned behavior. My mom had addiction issues, not just with alcohol, but also later with prescription downers. Both my adopted sisters had serious drug issues and one was an alcoholic. Since we don't know their biological parents, it is hard to say if there was a genetic component or if it was simply learned behavior. One of my sisters died a couple of years ago. Although her liver was toast, she died from oat cell lung cancer. My other sister has been in recovery for 20 years. She still has addictions but at least not to anything illegal at this point. She doesn't drink alcohol either.
I have never used drugs. I do occasionally drink too much. I monitor myself to be sure it isn't becoming a routine. I don't have an addictive personality. When I smoked cigarettes as a young person, it was simply a habit. I had no trouble quitting. It helps to be a control freak. I want to be the only thing or person controlling my life.
