So, OP, did you decide what you are gonna do or say? This one kinda blew up. I dunno, as a guy, if i was going to her place, I would ask her if she wanted to stay. I'd ask her if she wanted me to stay if we were at her place. It's nothing big. Just “hey, you want me to stay the rest of the night, or should I head out?” Just keeping it casual. He might even say something before you have to.
