Are my boyfriends friends testing me?

I’m (26f) visiting my boyfriend (23m) for a few weeks, we live in different countries and haven’t seen each other in a long time. Since I’ve been here, his friends blow up his phone daily to play games, go to the bar, or even go camping for an entire weekend, despite knowing we only have four weekends together. I don’t mind him spending time with them, but it’s starting to feel like they’re testing me or seeing if he’ll “choose” them over me.

One friend calls him a simp if he turns them down. They’ve never had girlfriends, seem immature (TikTok edgy humour 24/7), and oddly started going to the bar only since I arrived. When we all had lunch, one friend seemed to be testing me with offensive jokes, my boyfriend agreed but the “jokes” (creepy w minors, “back to the kitchen” to the waitress) got weird/old after the fifth time. Would always look at me to see if i’m laughing but other than that they didn’t interact with me at all. Are they trying to see if I’m “cool” with being sidelined? Or where his “alliances” are? Feels very “bros before ho’s,” which isn’t normal in adult relationships.

If this is the case, what is the opinion?
