Here's the situation. I have the kids over New Year's. We were all invited to a big overnight party, and were looking forward to going. Unfortunately my youngest daughter came down with something and can't go. My W offered to keep her tonight so I can take the other kids to the party. It was more selfish than generous, as she was sad about the thought of spending New Year's without any of her kids. She was planning on going to a friend's party, but she said she'd bag that and stay home with our daughter. As usual, it was slightly manipulative, as she wanted me to feel like she was the more giving parent, sacrificing for our daughter. I considered taking all three kids tonight, not going to the party, and having a fun night with just us at my house, but in the end I thought NO WAY! If my W wants to offer to take our sick daughter tonight, that's fine, I will go with our other two kids to the party and have a blast. If she wants to think that makes her the better parent, let her.
