Update:

Its been two weeks since he moved back in with us and all is going well - we had one incident in two weeks but I take the blame for that one as I could not stand hearing my granddaughter cry and cry (it broke my heart) so I got a little more involved in the issue than I should have and my son stood firm and let me know who the parent was in that case... I back off, she stopped crying in a few more minutes and I later apologized.

This week started his first week of looking for a job... he has placed seven applications to jobs that seemed promising - now to wait for Thursday so he can do a follow up call to them all.

Keeping Fingers crossed... Oh and I gave him one of my household chores to take on as part of his family responsibility while he is here - THE DISHES!
