stop staring at his cock. Um... That too but yeah. Act uninterested but not uninviting.
a guy is flirting with you if he is calling you nicknames or making you laugh
You keep on asking and hang out with him and they start loving you.
Keep flirting with him, try to get him to flirt with you and if he does he might like you. If he doesn't he might not be interested in you but he could just be shy.
A guy tells a guy to stop flirting with her. Or is it him?
That's no friend - dump her.
Can you tell if other guys are flirting with you? Nick's a guy, so I'm sure it wouldn't be much different than a lot of other guy's ways of flirting.
Flirting is flirting you do it the same way as for a guy.
Well, I would say to keep contact with him and just talk about things you and he likes. Not about anyone else or anything else. Trust me I'm a guy and I know.
In my opinion, there is no real way to tell. It has to be an instinct that you determine. For example, if the guy is smiling, possibly blushing, and not able to look you straight in the eye then he is trying to flirt with you and not scare you off. Try flirting back or start the flirt (lightly) and if the response from the guy is a flirt then keep it up : )
yesm
Not in and of itself, but it may be flirting in your case.
Many show off as a form of flirting. If a guy does things in order to get your attention, he is doing both.
