EW,
I was married to my drinking partner 14 years. I got sober, my partner did not. We lasted 6 months after I got sober and began recovery. I tried to be the supportive partner and went to a function with the old drinking crowd. I took my own car and left early. I declined any further offers. I was done and found that outside of drinking, I had very little in common with the old crowd.
When I finally had enough, I told him I was leaving. He offered to get sober if I would stay. I had to tell him that I always thought that sobriety was all I wanted, but after starting my own recovery from addiction I knew I wanted more than just a sober partner.
Congrats on your sobriety. May you continue to grow in your recovery.
