When Mia stopped moving, Gabe had thought she'd turn around to at least look at him but she didn't. She just walked away and then he let his shoulders down.
He heaved a sigh and walk into his car only to think more about Mia. Now, why was he so affected by her actions? She even cried because she didn't want him to play with her feelings and at that moment, he wanted to stop and do as she said. Go for another girl but for no absolute reason, he wanted her and no other girl.
She was beautiful even when she was crying and being the one to wipe her tears, he felt victorious so he smiled.
Now he didn't know if he was playing with her feelings or just getting to know her. He'd have kissed her earlier if she hadn't cried or hadn't mentioned that he should choose another girl.
