Raised voice at wife and am now in the dog house

[Nastynigel]

We were going shopping and my wife wanted to go one route but that would have taken longer, so we turned right instead of left.
My wife alleges I shouted at he when she suggested we turn left. I didn’t, although I did raise my voice to tell her she was wrong because her route would have taken longer.

I realised instantly I had made a mistake. We ended up cutting our shopping trip short, and she is now upstairs, crying and speaking to me

I’ve apologised but I’m being accused of shouting at her each week, although she cannot give me specific examples.

I was just annoyed at the kids fighting and her telling me what route I should take.
Advice? We seem to have a falling out every few weeks and it’s tiring for me and her.

As somebody who has been on the receiving end of it, it felt like it. Because it was. And that was why he did it - because he knew it hurt, it scared me and, well, it was enjoyable for him to have that as a way to make his dominance obvious to me, the kids and to everybody else in the vicinity.
