She's not following the custody schedule and I don't know how to handle it
My ex has been doing this thing where she randomly decides to keep the kids an extra day or two because 'they're having fun' without asking me first. I get that it sounds nice but I had plans and I didn't know if they were coming back. I tried bringing it up and she said I was being controlling. The custody agreement says alternating weeks. Do I need to lawyer up over this or am I being that guy?
That's exhausting and honestly it's not fair to you or the kids. They need to know what to expect. You might need to have a serious conversation about sticking to the plan.
