I second Lexi's statement that she would wish him well, but would go on with her life. Posters to SR first taught me the 3 "C"s, then that the problem is progressive, and finally that I can only live my own life. In the meatime, I've done a lot of work to figure out why I put up with it for SOOOO long, and that work has paid off.
If XAH showed up at my door today, full of apologies, appearing to "get it" finally, I would wish him well, I'd tell him that I pray for him every day, but that I'm not the same girl...and I won't be that girl again. And I would close the door--even though we were married 29 years with 4 children. He is toxic to me and I no longer knew who I was.
But all of this takes time, help from Al-Anon, counseling or both, and knowing that you deserve better--whatever he decides to do with the rest of his life.
Hugs and prayers coming your way.
