I know it is such a tough thing because your codependence kicks in and you feel so mean and awful for leaving him but you aren't mean or awful. You have done SO MUCH already and the fact that he refuses to get help shows you he is not willing to get better. YOU deserve to be happy and not have the dead weight anymore. Will it be hard? Yes. Will it hurt? Yes. Will you be happy and carefree soon after YUP! I think you've pretty much done as much as you can and now he has to learn to take care of himself. many rehabs now have dual diagnosis so he can get help for any disorders he may have. He has to want to get better though and as long as you finance everything for him and make his life cushy, why would he want to do that? Time to start thinking about what is best for YOU.
