I feel for you. That has to be hard, but at least you know he'll keep coming for half of the month (for another 13 +/- years). I don't think I would have managed the week on /week off arrangement well at all, but now I'd take that arrangement over this if UT will go for it.
It's not like it's quite, empty or lifeless here now. I have two other teens that have a pack of friends attached to them like appendages, and my house is the hub for my friends too. I just wasn't expecting this. I don't even want to go upstairs near her room. It feels like the vacuum created by her absence would suck me right out of the house.
Damnit. Here, I was thinking how lucky I was to be enjoying time with my teenagers when so many parents can't stand to be around their own for more than a few minutes. I should have known there was a catch.
