Hi Teggie
All I can say to you is how proud I am that you have made the decision to move on and put your children and yourself first.
There isn't anything you can do to save him if he doesn't want to be saved. The only one that can help him now is HIM!
The way he is living is his choice. If he doesn't like the living conditions, he can change them, you cannot!
I liked what Freedom1990 wrote!
Where there is a will there's a way!!
Besides, he probably doesn't even realize his living conditions are abominable!
Keep moving forward.
Hugs, Devastated
