How about allowing him to take care of himself? It might be the most supportive thing you could do for him in the long run. Treating a man like a man is not turning your back on him. He doesn't have terminal cancer and I assume he's of average intelligence. He can do it. He really can.
Once my ex quit putting all his energy into trying to get other people, or the system, to take care of him he actually started to get his life together. I had to stop taking care of him too.
I took care of my husband all the time. To a fault. In hindsight I really see it as one of the more damaging things I did to him and our relationship. I undermined him in about every way possible. Of course he went on and ON and ON when I quit doing it. It was eye opening. It made me a little sick to see him go on like that and even more so to think I encouraged it.
If you guys were so toxic to each other why would you think living together again so soon would be a good idea?
