I believe everything that was said above; some of it I have seen in my H's behavior, some not. But let me get this straight. He paid the bills and DEDUCTED that amount from the amount of CS he paid, paying instead with receipts? Big Whoop. If I am understanding that correctly, all he did was a little bit of legwork, like licking a stamp.
IMO, it will still be in your best interest to get the bills changed to your name ASAP.
As for your daughter, I'm sorry to hear she decided to go,but she may come back with a perspective you would never have gotten otherwise. As Forrest Gump says, "That's all I'm gonna say about that."
Try to get some rest time and enjoy yourself this week Seeking. Worry is like a rocking chair, it gets you no where, but gives you something to do. ((Bless You))
