I usually take my daughter to school in the truck, and he usually walks his boys because their school is close (a block away). Either way I am home before the boys even walk to school. 

So last night my boyfriend and I were arguing and he out of spite told me that he was taking the boys to school in the truck, then going to his doctors appointment right after. I told him that it doesn't really matter if I use the truck or not because I am home before they leave anyways, but he told me to send my daughter with my sister to walk to school.

So this morning was like a foot of snow, blizzardy snowstorm. I knew there was a shit tonne of snow outside, I bundled my daughter up to walk to school with my sister and her kids. I didn't inform my boyfriend of the insane amount of snow on the truck that he would have to clean off (which I usually do). He left with only a few minutes to get his kids to school, and he saw all the snow and lost his shit on me. He then called and bitched me out for not telling him ahead of time. 

So AITA? I honestly don't think I need to inform him on everything considering I'm not his mother.
