D10 stayed with exSIL yesterday because she had a snowday. When I picked her up, she says "Mommy, auntie said we could come to her Superbowl party!" So she is standing right there and invites me and says you guys are more than welcome, but I'm sorry she put you on the spot. I said yes on the spot, because I didn't have plans. She says it's a big bash.
I asked D10 in the car how the invite came about. She said she was talking to her dad that she wishes she could go to her aunts superbowl party because it is so much fun. He said if you and mommy aren't doing anything, you can come. Then he said Your mom could come to, let me just ask your aunt. Which he obviously did and she said yes.
So it turns out I am attending a party with ex and OW. The upside? I am hoping my exSIL's husband has some cute single friends there.
