I did tell him before he went in that if he didn't finish the program he couldn't come back to our home. But I know there, in the moment, if he wants to leave, he may feel differently. I have set some boundaries, but really I'm new at this and don't really know what to do. I've also always been weak when it comes to him. Not to say I am a weak person or dependent on him in any way. But I just tend to give in to him. But I must say I have gotten 150% better at that these past few months. And he does know that I am on the verge of leaving him. He told his counselor that at the rehab center too. So he is aware of how serious I am.
