Hi Margie and welcome.
Right on. His success will not depend on whether you are living with him or not. Have you thought about attending alanon? If this is your second alcoholic marriage maybe there are some thinking patterns you could look into. You might also want to pick up a copy of Melody Beattie's book "Codependent No More" and see if you recognize yourself in there.
Make yourself at home and please feel free to share and ask questions here anytime.
Hugs,
Smoke
