Boyfriend wants to go to the club with his friends...

My boyfriend hasnt seen one group of friends for a while cause some friends moved away. Theyre all going on a trip together for the weekend to one of his friend’s house. He said that the guys want to go to a club. I dont like the idea of my boyfriend being at club without me cause, to me, it’s where single people go to find someone to mess around with after. I know he’s not going to do anything but i think if he goes alone then it kinda sends the message that “hey im available” to all the women there. I think out of respect for our relationship he shouldnt go. I wouldnt go to a club without him to not make him uncomfortable to begin with. I told him he can do whatever he wants since hes a grown man but to know that i’m not okay with it.

Am i being reasonable? Do you think im being jealous? Just looking for another opinion since in my last relationship i was basically gaslighted for ever feeling anything.
