Switching weekend visits with ex

My ex has supervised visits.

He moved 7 hours away to Kansas.

He is suppose to come into town tomorrow for his visit and his parents are supervisors.

He let me know this morning he will not make it therefore he is switching weekends with me because his mother has a sinus infection and bronchitis. Which is very common for her this time of year. ( she is young (42?) and very healthy! )

I ensured him that even though his mother is not able to make the visit his stepfather is also labeled as a supervisor so he could also come down with him if needed so he did not miss his visit.

He said no as he is not her paternal grandfather.

When we made his final agreement we put down his mother and stepfather. His stepfather has been in my daughter’s dad life since he was 2 as his biological father passed away when he was a baby. This agreement is for his step dad and his mom. The court is not aware his father passed away because it has been his stepdad since he was a baby. No one knows that is not his biological father.

BUT I can also give written permission so I offered to do so for his stepdad to make them feel better and he said “no I am not leaving my mother who is sick.”

Okay I respect that but I am not able to change weekends. I am moving storage units this weekend as well as my final month of my semester and I plan my weekends and schedule my exams for the weekends my daughter is with her father. Thankfully my parents are around this weekend to help during my studies but next weekend is when I have everything planned for us.

He’s making me feel super bad. I usually switch I’d say 60-70% of the time but with exams and holidays I am not able to this time. If I did switch he’d have her next weekend and the following weekend and the following weekend visit is extended for 6 days so he’ll have her until Wednesday for the holiday. I don’t feel so bad as his mother is an adult and I gave him a few options to make this weekend work but he’s going to call me tonight and I am a tad nervous of how he is going to react to me.
