Is it normal to be treated like this even if i am nice?

I will never understand why "liking" people's shit on Facebook, means you want to bone them. I shall never comprehend such weirdness. If I like something, I like it. Doesn't mean I want to marry them or some shit. >_>

Here's an idea, ASK HIM.

ASK HIM if he's interested in dating you and if not then stop creeping you out staring at you.

Sounds like he is but he lacks confidence.

Then again maybe he's mental.

When you ask him out maybe he wants to go but doesn't have any money so he makes excuses.

Who knows, that's what communication is for.

Post his facebook here so we can see how he looks/acts.

If he won't suck you off I will!

Lets look at your question for a second.

"He, on the other hand, goes out with girls with boyfriends, likes their things on facebook, talks to them. It's always girls with boyfriends."

"Girls with boyfriends."

"GIRLS WITH BOYFRIENDS."

I can't believe nobody else pointed this out yet. Maybe he isn't interested in you because, rather than looking for an actual long term girlfriend, he is a player who loves ruining relationships. He is always chatting with girls that already have boyfriends, maybe even flirting, so he could ruin their lives. So, in conclusion, he treats you this way because:

1.You don't have a boyfriend, and I'm pretty sure he likes to make girls cheat on their lovers. So, no boyfriend means he can't ruin a relationship, and doesn't have any interest in you.
2.Since he loves ruining relationships so much, I'm 99% sure he isn't looking for a long-term relationship.
3.This is always a possibility, since I have met many dumbass jocks who are actually like this, so don't cross this theory out.

Of course, it could also be that he is just more comfortable talking with girls who already have boyfriends because he is nervous around single girls who might try to flirt with him. Since he's uncomfortable around you, you might actually be right in your assumption that you are intimidating him a little. Try acting a little different around him and see if that helps. If it doesn't, consider my first theory.

Just be like "Why???????????????"

He might well be interested, which is why he finds it more difficult to behave naturally around you than he does other girls (especially the ones who aren't available). The easiest way to find out is by asking him. You could also try asking other girls who know him if he behaves that way around them. If you find his behaviour creepy or unpleasant, let him know and ask him to stop. Be simple and direct about it.

Get him to lick you bum!
