Only the most
honest response is the right one. If you were indeed picking up on her, you could only respond with a "yes I am, and I will indeed try my best, how do you think I'm doing?". You can never say "no", because it will either tell her that you are lying or not interested. Both options are bad. But on the other hand, it all depends on what outcome you want (getting the girl is not always the best outcome, some girls are best avoided). Maybe this was for the best anyway.
I think this is what happened in your case:
1. You started talking to a girl and she (probably) enjoyed it. She felt wanted and liked it.
2. For some stupid reason she made the mistake to give you that comment that you were picking up on her. Girls who know game should never say such a thing. Blame on her!
3. When you denied it, her ego fell apart and she felt hurt. That's the reason she started squawking. What did she expect? She probably didn't know herself. That's why a "yes" would have been the "best" answer. Blame on you!
4. You made it even worse by ignoring her. But on the other hand, I would have ignored her as well. Maybe I would have told her "I'm sorry if I disappointed you, but... Get over it!", haha! A girl with such bad control over her feelings will most likely cause trouble in a relationship anyway.
