My fault or just childish?

I am scheduled to go in for a cervix rippening today at 4:00 p.m. My husband and I were able to get rid of all our other children except 1 (which is the youngest) she doesn't attend school. My mother decides to keep her for me so she lives like an hour and a half away. We head there around 8:30 p.m. last night. Now we got into a argument on the way there. He literally turned the car around and went all the way back to our home and didn't take our daughter to my mother. He has school that he leaves for very early in the morning and he just tells me that its for my benefits that he was taking her down there. Now I have no way of getting her to my mom today before 4:00 p.m. and he doesn't get out of school until 5:30 p.m. I'm mad as hell... I'm I wrong? I take part in the argument but what did that have to do with getting our daughter where she needed to be?
