When I quit, my dh blamed *me* for changing things. He did not sign up for that and was not going to stop drinking just because I did. I didn't expect him to.
18 months later, though, he was miserable and sick of seeing me so happy and free. He decided on his own to get sober, too.
I am so glad I focused on me and what *I* needed to do. My spouse was going to come along or not. I couldn't worry about that in the beginning.
