We don't know if it is a serious relationship. However, the guy does come across as if he has a crush on OP. Why has he been flirting with OP for 6 months and has never mentioned his girlfriend? The only reason I can think of is because he likes OP as well.

I don't know. I've known a LOT of girls who think every guy (or at least, every guy they like) is into them. Some girls equate being nice with flirting. It's a common occurrence.

#11 is right, I was thinking this girl misread everything and didn't think anything about it.

Sometimes, some people consider friendly banter as flirting, while the other person doesn't see it that way. Or maybe they have a flirtatious personality, where they engage in harmless flirting without realizing it. Given that he's been with his girlfriend for 5 years, and was willing to introduce OP to her, I'd say that any perceived flirting was unintentional, but rather, he saw OP as a potential good friend.

@11 People misinterpret my playful silly personality as flirtation. It gets really annoying at times. I think I should put a disclaimer on my shirt or something.

#4 What?! Haha... How did you decide that he came across as having a crush on OP?

Maybe OP needs to watch the movie He's Just Not That Into You.

Thank you, Perdix, for getting the song " Single Ladies" stuck in my head right before I am going to bed.

21- times are a changing, no need to be conventional anymore. Also, nobody questions perdix or beyonce.

i want to say something but im mesmerized by ur profile pic...

Good friend? No, acquaintance. Good friends know when you've had a girlfriend for five years.

Girls have done this to me before. Needless to say I wasn't flirting....

I'm not sure you'd want to have a chance if he's happy to flirt with other people for months on end while in a committed relationship.

Just be careful you don't break any hearts haha. My ex used to flirt like that too and he saw it as harmless, but a lot of the girls he talked to ended up liking him because of it even though they knew he was taken, and he also ended up cheating on me eventually. I'm not saying that you would cheat, just be careful with those things and really make sure that it is harmless.

^wut?
