Should I be annoyed?

The father of my oldest two kids and I agreed for the past week that he could keep them for the first half of the Super Bowl so they could spend time with his family for there Super Bowl party which I was totally fine with I had no problem with his dropping them off later than normal so they could spend time with them well I text him that I’m on the way to my house at half time so he could head over and bring them to me and he gets mad saying I should come get them! Like no we had it planned all week that you were bringing them to me since you are the one who had to keep them later come to find out he didn’t wanna leave his new girlfriend at his moms house while he dropped them off. And usually I don’t mind picking them up but I’ve helped him out every single day this week picking them up even on his days and for him to just expect me to keep doing it annoys the crap out of me plus he’s been so rude and disrespectful to me the past 3 days and doesn’t appreciate me helping him and his family out this week. Also it would mean I would go passed my house out of my way to go to his parents house to get them. Am I being unreasonable or I have a right to be annoyed ?
