It's not your fault. You can't change him. He is an addict doing what addicts do. He is stuck. And you are codependent on him, and just doing what codependents do. It's a viscious circle and you both are part of it. If nothing changes, if nothing changes. And that means you have to change if you want things to be different. It's hard but if you do it one babystep at a time, it is much easier. Keep us posted ok.
