I wouldn’t say there’s a norm, everyone varies. What would probably help a bunch is some sort of validation for how that fight sucked for the other person, no matter who’s right or wrong.
“Hey, I’m sorry we fought. I hate it and I know you do too. I don’t ever mean to make you feel bad. I love you and want us to be ok. Is there anything else you need me to understand?”
The truth is that Trump has done more for conservative causes than any president prior. He installed the far right justices that have toppled Roe v Wade and affirmative action. He enacted things like the Muslim travel bans. In short, either they know he’s a scumbag and don’t care because he gets results, or they don’t believe their own lyin’ eyes because look at the results he produces. It’s all about the bottom line, and the ends justify the means.
