The first 2-3 weeks after that conversation, I checked pretty frequently. He had also cut off a bunch of "friends" and I knew he was having withdrawals. Now, if I happen to be on his laptop for something, I might look at his FB and email.
But honestly, his actions and his words have changed so much since DDay 2 that I'm 100% positive that he's not doing anything "bad" right now. That can always change in the future though...
I think it's a positive step!
