Should I stop going to the bar if my parter doesn’t like the bar?

So I’m a senior in college right now (so is my fiance) and I often like to go out to the local college bars with my friends. I never get too drunk I never get sick and rarely have hangovers. I live really close to the bars so I also walk home and most of the time my friends walk me home (it’s only three blocks). My fiance really hates the bar, and I never force him to go and never really push because I know that’s an environment he doesn’t want to be in. He has a lot of trauma surrounding the drinking/partying stuff because of his parents which I totally understand and which is part of the reason I always make sure I never get too drunk. We have pretty open communication and he says he doesn’t care when I go, and doesn’t mind my weekly girls night, but every time I come home (usually around midnight) the next morning he’s really standoffish. He’s not angry or anything but he just seems off like it bothers him but every time I ask he swears it doesn’t.

I guess I just want some advice as what to do. I love hanging out with my friends and love the bar scene in general, but I hate making my fiance uncomfortable. I don’t want to miss out with my friends on my last year of college because a lot of them are leaving in spring semester. I also love this man more than life itself and would stop going in a heartbeat if he asked but he keeps insisting he’s fine with it.
