Most Helpful Guy
For me, it when I can't stop thinking about her in more than a sexual way. Maybe that sounds weird, but when I first started dating a girl, when I think about her throughout the day it usually something sexual. But when I find myself just thinking about her and smiling, or something silly she said, or some quirky little habit she has and I sort of laugh to myself. When I suddenly just want to hold her and have it not be sexual.

When sex with that girl is not the only thing on their mind, when they can spend hours talking to her and get jealous from other guys she likes, I guess !! Guys, correct me if I'm wrong.
