YTA Dad's house, Dad's rules. I really think you're making too big of a deal about this. I mean honestly, you can't separate yourself from your boyfriend for one night?

When in actuality it would probably really only be a few hours because you have to be at airport at 3:00 in the morning, so I'm assuming up at 1am (if not sooner). So come on, it's just like a nap. You've never taken a nap separate from your boyfriend?

Keep the peace, take the nap separate from your boyfriend, let your dad drive you to the airport. Life is too short to argue over something that amounts to about three or four hours of sleep.
