Just wanted to see how things went.
When my dd went for her first overnight it was actually harder on me than it was on her. I hope that was the case here too, and that things went great for him!!
(And it will get easier for you too. My dd spends eowe at her dad's. The first few months I cried every time dd left, but now I use that time to rejuvenate myself, and actually look forward to my empty bed on Friday night. Of course by Saturday night I'm ready for her to be home, but it's not nearly as hard as it used to be.)
DD: I'm bored and want to play Me: What about me? I can play. DD: No thanks, I mean a real person.
