Why does this guy lead every girl on?

[Cyиίcαℓ]

So this guy on facebook is my friend and all, i don't know him very well, he just randomly added me and started chatting with me. When i type something on his facebook he'll reply back like: thanks, baby or other wise he'll type a bunch of hearts on my page. But he doesn't only do this to me, he does it to almost every girl he types to. He flirts with them all. Wtf? is he trying to make us all his b*tch or something? I thought <3 means love not hi whore?
When I message him he doesn't flirt with me, he'll only flirt with me on my wall, which is public. What's his deal? Who the hell does this, is this normal?
he added me because he's seen me at school and he associates with some of my friends.

He's bored and is seeing who will take the bait and pursue him. Just ignore/block the guy.

He just wants attention...

well, i met my gf on Facebook and though she claims i was "so hitting" on her all i was really doing was adding people from my school. I'm just a good talker. It's nothing personal i just know how to talk to people. And though i really like her she is wrong about our first encounter. It's just that females think that men only want sex from women. They think that is the only reason why a man would talk to them. So when they see a man talk to women they think. SEX,SEX,SEX SEX SEX, FLIRT, FLIRT, FLIRT

Strange how that works isn't it.

It's really the last thing on my mind.

I'm not really flirting. I talk to everyone the same way. That's just how she took it.
Truthfully if she didn't ask me to ask her out i never would have known she was interested.
Because i wasn't looking for a girlfriend. I was just being nice.

This sort of taught me that women don't know men nearly as well as they think.
