I told her that I never went because I was watching the kids otherwise the kids would be all over the place and we wouldn't be paying attention if the went with us.
So who is watching the kids? Or are they going with you?
If it was me - I would go, sit separately and continue to be the best dad I can be. Or I would watch the kids.
This is about the kids and what is best for them, not about you and her.
