I want her to be my girlfriend.

"I want you to be my girlfriend," you say.

"Oh!" Belinda says. "That's so sweet! I'd be proud to be your girlfriend tonight, Parker." She gives you another kiss on the lips.

"Well," she says, "mustn't keep Molly waiting."

She takes your arm and the two of you walk outside where Molly has the car waiting for you. Molly opens the door for each of you, gets in herself and starts the car.
