Our first year was really tough. Husband sober for 8 years at that time. Honeymoon when we weren't living together, quasi-nightmare when we did. At the core of it was undiagnosed BiPolar II. Looking back I see that RAH had many alcoholic traits a 'dry drunk". I stayed in it I don't know why. 3 months in I was ready to leave. I did love him and he me. I think I was more committed to not failing. 10 months in he was diagnosed and medicated properly - I was done at that point but gave it another shot to see if it made a difference. It did. We had a relapse last year but it was a MUCH better year than the first which I owe to going to Al Anon and changing my codependency which was causing so many problems - I didn't see this until I joined SR in September last year - I really thought it was all him.
I am happy, very happy we are together today. One day at a time........
A co-dependent and a RA is a bad, bad, bad mix. Work on yourself - detach from him a bit - see where it goes. If he continues to profess that he doesn't love you then I would exit.
