boyfriend won’t wake up to let me in

I let my boyfriend know around 9:30pm I was on my way to his house (an hour away) and now that i’m here, he fell asleep and won’t answer/wake up to my texts or calls and I have NO way of getting inside.

I can’t knock on the door cuz he himself won’t hear it but someone else in the house will and that means I’ve woken them up (and possibly the kids) which is a no no and just rude. and they have cameras so if I knocked and no one ended up actually waking up and answering they’d see me knocking and then lurking on the front porch 😭which is embarrassing and again, rude!!

I don’t wanna be a creep and go knock on his bedroom window because again if he doesn’t wake up, i’m a freak for standing out there knocking on their window!!

WHAT DO I DOOOOO ??? sleep in my car????
