My teenage ex bf and I rowed once. I was drunk and chucked his drink away (I was tantrumming basically) and he lost his temper at me in public, shouted at me and grabbed me by the shoulders. We were 19ish so yeah.
My exh and I had some very unhappy years. He could be a dreadful misogynist, hugely jealous and controlling, manipulative etc. But we never had a single row in public. He slightly raised his voice to me about twice in over 10 years, in private. I probably did the same 3-4 times out of frustration rather than anger. We never name called. We did have some really painful upsetting conversations, we were not happy but we didn't have rows.
My current dp and I are 4 years in. We have never had a row or angry words. He says something that upsets me about once a year, I tell him he upset me and why, he says sorry and then it's fine. I finally upset him myself about a week ago by comparing myself to someone he dislikes. I noticed he was getting worked up and said sorry. That was it.
My parents never argued in front of us. My dp's parents, same. My exh parents, same though his dad could be really difficult.
Violent, nasty arguing is something that can be really common in certain communities / families, and totally unheard of in others. Arguing is a skill, you learn it from others so it's a case of having role models (for good or ill).
