Guys, would you do this?

It may be that he simply enjoyed the conversation and wanted to hear your thoughts and opinions, nothing to do with liking or disliking.
I talk for hours to women who enjoy discussion, some at the extreme end of the scale I would not want to talk with on other subjects but this may be a shared interest, at the other end of the scale I might want to meet to continue the discussion ... but it doesn't have to indicate anything more intimate on either side. That is taken care of by her body language, if she has her arms folded and little eye contact then it is simply the pleasure of sharing an understanding or debate that she wants ... if she sits close and is open in the way she holds herself with plenty of eye contact and just maybe a light affirmative touch on my sleeve then I feel more likely to want to see her again to get to know her better.

Interesting. Most girls think that if a guy stands next to you and says three words to her that he wants to f-ck her.
Even if those words are "i hate you."

Your answer is it depends. Is he touching you?
Is he looking in your eyes?
Is he checking out your body?
Is he checking out other women?
IS he the one who started the conversation?

If he is online and chatting online, then there is really no way to tell other than just asking him.

the guy's probably interested in you. on the other hand, maybe he's just looking for a platonic friend. see how it goes.

he's either interested, or just finds you to be an interesting person. either way, he didn't get sick of you, so that's good.

If you just met, then I think that he likes you; its just that he doesn't know that he likes you yet.

What you just experienced was the start of a relationship, and no I don't mean a boyfriend, it's a conversation go with it and see where it takes you, if you over analyze he'll feel pressured so go to where it takes you, because it sounds like you might like this guy

i would talk to a girl that long even if we were only good friends. but who knows, there could be something more. just ask him

He could be bored, he could like you or it could be something else, there is no way too tell just by how long he talks to you..

Perhaps I will talk/chat with a girl whome I misunderstood, like in this case there is a probability that he like you. well I think it is fifty-fifty.

Everyday-he likes you
just that one time-he was bored

Well personally I think he the guy must care about the girl enough to talk her for a long period of time. I say that because they guy I like and I talk for countless hours on Skype, AIM, MySpace or even Facebook. Plus I do know that he likes me back, its just a complicated story why we aren't really together. But yeah anywho I say if a guy talks to you for more than 2 hours he cares about you. Even if you just met him.

I wouldn't say he likes you because I talk to guys I just met for long periods of times or even late but you never know. My advice, just ask him if he's interested in you.

I was on skype with a guy for like 5 hours once and he never called me again after that. It's hard to say, but one thing's for sure; don't smother him or act clingy otherwise you'll send him running the way I did! He even told me he was interested in me but I'm guessing those 5 hours on skype really did him in, haha.

Like how late? But I don't think a guy would stay up to talk to a girl he doesn't like just cause he is bored. I would say he like's you
