I've said exactly the same thing before. In my context it meant 'just say it', because if we're just going to be friends then there shouldn't be flirty game playing. This way it seems they probably want to be nice to you, rather than "I don't like your face".
Yes I did , to that chick who kept following me around the club. Then I just asked another girl to pretend to be close for a few minutes to get her to go away! lol
If I was not interested in a girl, I would say nothing to her.
probably because he thinks you want something from him, but he doesn't know what it is... and maybe wants to know what it is. Its not the same thing as not wanting to talk to you or not being interested.
Maybe he is feeling frustrated. Don't take it too seriously. Just move on and leave him alone!!! Some people need more space than others and who knows maybe he'll end up missing you and if not it's his loss.
Emotion over logic. He was so annoyed he couldn't think. And no, I wouldn't.
