Oh sweetie, I am so sorry for you and the boys. My prayers are going out directly for both of them.
I still have the hope your sister will be calling you, or the police...(maybe they can keep you informed?)
I think your sister will call you, because she doesn't remember that 2 small children have a way of tying an addict down.
Prayers, and big hugs...
