I know this is long, but I’ve got a huge test tomorrow that I need to sleep before but instead I’m freaking out about this. Please help!

So my boyfriend of 1 year and I are going to prom together next weekend. After, I was gonna sleep at my friends house and he was gonna get an air bnb with his friends, and I was fine with us being separate. But now he can’t do the air bnb with his friends for various reasons, so he wants to go to a party this girl he’s becoming friends with invited him to at the house of her (platonic) date.

After, he thinks he’s going to sleep in his car because “what if he’s high.” I’m really worried about it... I know he wouldn’t cheat on me when he was sober, but I can just imagine this girl convincing him to sleep over and things escalating from there. Or he gets in his car while high and starts driving...I don’t know, I’m just so nervous about it.

My only other option is for him to sleep at my friends house with me, but I’d feel rude inviting him into her home.

What should I do?
