(41f) husband (35) can be a real jerk when he's angry about stuff. Normally I just ignore him but I'm angry about what he did to my niece(10) yesterday. We were driving her home down some twisty roads, I was in the back, she was in the front(my fault, I should have insisted on the other way). She fell asleep and began leaning over to his (drivers ) side and at one point he had difficulty steering when a car came close (I repeat the road was narrow) and he had to jerk her awake. He was livid, I get the immediate reaction as it was quite frightening but this continued when we got home. She was crying, he refused to hug her and she was too upset and sobbing on her mother. Imho he was much too hard and now neither of them want to speak to him, I'm upset about this as my niece doesn't have many male role models in her life and until yesterday they were good friends. If I know him he's going to dig down about how wrong she was to fall asleep, I want him to see that, while it was frightening, as nothing happened his reaction was over the top and at least to apologise for making her cry. Does anyone have any advice for how I could start to discuss it?
