Good for you!!!
My STBXH pulled something similar. He took a personal day today to go to some sports event. He asked me last week if he could see our kids, for a few hours in the evening, even though it isn't one of his scheduled days. We are only a few weeks in and I don't want to keep the kids from seeing him while they are adjusting. So, I told him that would be fine, given is a special circumstance.
Anyway, he tells me yesterday that he probably shouldn't take them because he doesn't know how long the event is going to last or when he will be home. Blah, blah... Turns out Miss Hotpants was going with him. That's why he didn't want to kids.
At first, I was so heartbroken. This is the second time he has bailed on them. Thankfully, I didn't tell them beforehand. But, then I thought, why be sad? Its more time I get to spend with them. So we played games, listened to music and danced. I have to make their lives good because he is already proving that he only cares about himself. Me: BW
