I have never reacted to anyone else the way I react with my wife. With anyone else, the mix is different, so different reactions take place. (Also, kids aren’t involved.) I have no guilt about my reactions. They may not be ideal, but that’s me. She has her role in all this too.

Nod. Yes she does, and I understand the not ever reacting like this.
Not having remorse/guilt/culpability for your caustic emotional reactions is ...I hate to say it... a Narcisstic trait though. You dont have to feel shamed(pride) of them, you can say yep I did that, it was an error, and I need to work on it, but going beyond and not caring is very damaging to both you and her.
