I, 38F have two bio kids 13F and 11M from an unsuccessful marriage I was in when I was very young, and my current husband, 42M has two kids from his previous marriage as well, 12F and 8M. The mother of my two step kids takes them in every other weekend to spend a few days with them as my husband has the majority of custody over the kids.

I booked a camping vacation for me, my husband and my two kids to spend a weekend outside, as that weekend my step kids mother was going to have them.

My step kids mother calls us and tells us that an emergency came up and we’re going to have to keep the kids for that weekend, even though I didn’t book them for the vacation. My husband says to change the reservation since cancellation time had passed (72 hours), I told him that I wanted to spend more one on one time with my kids and that this weekend was supposed to be for that. He said that his two kids are now a part of our family and we had to include them, but I refused to change the reservation.

AITA?
