Borgs, I agree with the above poster, he is what he is and he has made it clear what that encompasses. The big question here is what can you do to take better care of yourself and detach from such a toxic relationship...or risk going down with him.
Love cannot save our addicted loved ones, if it could not one of us would be here.
Please take very good care of yourself, the pain of leaving a relationship with active addiction is great...the pain of staying is greater.
Hugs
