I'm really sorry. That does suck. Your H is in complete selfishness mode. I can't understand not wanting to be with my kids either. If he's that self absorbed, you are going to be MUCH better off without him. And so will the kids.
You aren't alone tonight. You have us. I'm not going anywhere, and will be hanging around here tonight as I watch the football game. There's a whole bunch of us here who won't be kissing an adult tonight at midnight (if I'm still awake!).
As hard as it is to see your H pull back from the kids, just know that as much as you want to shiled your children from hurt in this world, that is not something you can save them from. But, with you supporting them, they are going to be just fine.
I'm viewing tonight as the start of a new year that most certainly will be better than 2009. I won't let it not be that.
Hang in there. We are all going to have a much better 2010.
