Thanks everyone.  I'm working on boundaries with him & trying hard to do what's best for the kids.  It's hard because he says I'm throwing him to the wolves & will not & cannot make it without me & that he has nothing without me and that if I give him another chance he can be the man I fell inlove with.  But, Honestly he's said that before & then always goes back to the drugs.  I just need to stay strong & live for me & the kids.
