Questions: Guy's Behavior

Let’s say there’s a room empty save for 10 men, and they’re all talking about various things. One man makes a derogatory joke about women, the usual thing where the punchline is women are stupid/sluts/only useful in the kitchen.
Three men laugh at the joke, because a good joke is a good joke! They’re not going to let political correctness stop them from enjoying a good laugh.
The remaining 6 men are made uncomfortable by the joke.
Three of those six still laugh in a sort of uncomfy chuckle, they don’t want to be left out of the group even if it’s kinda gross.
The other three remain silent, they don’t want to encourage that kind of behavior by laughing at it. They change the subject.
At the end of the night, all ten men go home, the joke is not mentioned again. Who are the good men?

Can narcissistic abuse affect you even if the connection only lasted three weeks? Is it normal to still feel impacted by how someone treated you?

I experienced every stage of narcissistic abuse with him — the idealization (studying me, learning my trauma, saying all the right things), the devaluation (disrespect, throwing my vulnerabilities back in my face), and the discard (ghosting me and acting like I never existed). This wasn’t a normal “we talked and it didn’t work out” situation. It was deeply damaging. My mistake was being open about my mental and emotional wellbeing from the start, and he still chose to proceed anyway.

Or is this a normal dating thing? I’m so curious to know
