AITA or just overthinking?

I (26F) am almost 27 1/2 weeks pregnant and my bf (26M) said earlier today his brother and sister-in-law want him to go to the club tonight. I think I’m assuming how the club environment is since I personally have never gone (I have anxiety and feel like it might be a bit out of my element especially now that I’m pregnant) and am relying on friends describing it and tv shows which I know arent accurate.

Am i overreacting for being a little hesitant on him going? We’re both LGBTQ+ and have been together for 8 1/2 years, and we haven't really been intimate in the bedroom lately (not for any bad reason in my opinion just been a lot of things going on personally and stress). I mentioned how I was feeling to him earlier and said he’s going to just sit with his brother at the bar while his sister-in-law and her friend dance on the dance floor and he acknowledged us being in a long term relationship, I’m just still feeling some type of way and i dont know why.

We did break up for a year in 2023, but stayed friends while living together and eventually got back together in 2024. He saw some people while we were broken up but he’s the only person I’ve ever been with. He’s never chested but I did find him prior to our breakup looking at provocative pictures of people we knew on social media, so I think this is where my insecurity/overthinking comes from a little bit. He’s never physically cheated on me though and I try to remind myself I’m the one he wants to be with and comes home to. 

He just left to go there but he did buy cologne at walmart, got a haircut, and put on a nice outfit which I made a comment saying he doesn't get himself ready like that for me maybe thats partly why I’m feeling this way. He said he wanted to feel good about himself and that it’s because we don’t do anything or go anywhere (a lot of the times he makes plans with people to go places without me or when I ask to do something he doesn’t want to like play a game/watch a movie because it’s “boring”).

Then I said then why can’t you ask me on a date sometimes if you’d get dressed like this for the club and got a bit upset. I know our ideas of fun may be different but am I just hormonal/overthinking this too much?
