Tell me I’m overreacting

Okay please tell me I’m crazy or whatever because my boyfriend thinks this is no big deal. So my boyfriend, his best friend and two girls are going to the shore for the weekend. He didn’t invite me because he didn’t want me there which really hurts but whatever. So they’re staying in a hotel and there’s only two beds and a pull out couch. I told him I didn’t want him to sleep in the same bed as his female friend. Like it’s called respect 🙄 and he got mad and said that they don’t have feelings for each other so he doesn’t see the big deal with sleeping in the same bed on opposite ends. And that pissed me off like why can’t you sleep on the pull out couch?? I get he’s tall so he might have trouble sleeping on it but like really?? So we got into a fight about it. Like it’s not about not trusting but it’s about respect. If we were married he definitely wouldn’t be sleeping in the same bed as another girl. He texted me after I left and said that he’ll sleep on the couch but he if can’t sleep, he’s getting in the bed. Which I know he’s gonna end up sleeping on the bed. He never takes my feelings into consideration ever. Am I wrong for feeling this way??? I also asked why can’t I go and he said “it’s not that you can’t go, it’s that I don’t want you to go”... Am I wrong or overreacting or something?
