Why does a guy lead a girl on?

Anonymous
I know girls do it, too, but it's directed towards guys.

He did everything that would show that he liked me. He used to approach me daily, talk to me all the day and night, was concerned about my life and problems and would flirt with me. He made me feel special and different, and then one day, he just dropped me like a hot potato. It's not like he was even after sex, because he never had sex. He is still not dating anyone, and talks to everyone in such a friendly way but avoids me like a plague. If you don't want a girl to fall for you, why don't guys stop making her feel all the feelings, only to step back one day and ignore her without any explanation?

He doesn't want commitments, by the way.
