I thought I was helping

I went to my moms to do laundry for the day took all 3 kids with me, my fiancé got off work at 2pm came home to watch the football game and I was still finishing laundry at the time. I thought he needed some him time so I finished the laundry. I ended up at home around 7pm, he was very short and threw in my face "I didn't know you were going to be gone this long" and said "thought we were going to have supper at a normal time like 4pm" I said I was sorry and needed to get laundry done so I didn't have to worry about it this weekend... it made me feel really shitty I thought I was doing something good... I asked for some help with the kids for a bit while he was playing video games and he got all upset and angry telling me this why I don't want anymore kids. It made me cry and he's like yeah I know I'm the bad guy in the relationship...
