Posting this because I think I might be as much to blame as dh.
Argument in the car this morning after we had dropped dd off at school. Topic is irrelevant and was completely stupid. I pushed the subject (and pushed and pushed), he tried to ignore me and turned the radio up which was a red rag to a bull. I got angry and raised my voice, told him he was being entitled. He shouted back, no idea what he said, and I told him to let me get out of the car and pulled the steering wheel slightly to the left. Which was obviously stupid and potentially dangerous.
Dh responded by saying that if I did that again he'd punch me in the face.
I got out of the car and walked away. Had a tooth extracted today and he checked in to make sure I was ok. Other than that we haven't communicated. He'll be home in a minute and I don't know if I am right to be pissed off still or if I am just as much to blame.
(No history of any violence on either side previously)
