Ex wants to change custody schedule last minute AGAIN
This is the third time in two months she's asked to swap weekends at the last second. I had plans with the kids this Saturday and she texts me Friday asking if she can take them instead because her new boyfriend is visiting. I said no but now she's threatening to involve lawyers. Am I being unreasonable? I feel like I need to be flexible but also I can't just rearrange my life every other week.
What happens when you say no? Does she blow up or does she just expect you to go along with it?
