How do I flirt with a good friend?

Just be more sweet, kind & helpful and compliment him more that the other chick...I think he'll soon get the hint

Heh heh heh

Sorry but if I'm into a girl, I'm into her. And it that were the case you aren't gonna be able catch my attention until she's out of my system or does something to turn me off. I guess you can always try though. If he's not seeing her yet you can always just be open with him. Tell him how you feel about him. If there is a chance that he felt that way about you at some point it may rekindle an interest to hear you come out to him about your feelings. But I gotta tell ya. Still a long shot. If he reciprocates, and does indeed show interest in you, I recommend you go on a few dates with him to make sure you like him or that he likes you. Sort of a test. Otherwise I predict it will end badly.

So I gave you an option to try. Remember though it's still a real long shot. Still worth trying though. If he shoots you down, remember that it's not the end of the world, and who knows he may come around.

Maybe you should send flirty vibes if you're not already. Dress a little cuter when you hang out and be slightly more flirtier to spark his interest. If that doesn't work then I don't know what to tell ya

I don't know if there is a trick to that. Liking is base on attraction. If he is not attract to you before then I don't know if he ever going to like you back. My advice is just be yourself and don't pretend to be someone you'll not. Also never sleep with the guy and hope that he's going to like you back. I saw many girls did that and they just end up as sleeping buddy. Be yourself is the best tool here. now if he is going to like you because of you.
