So say if I'm flirting with a girl and I've made my interest in her obvious and she's not really responding in a way that would convey interest is there a point where I should just give up and move on?

Obviously if she isn't showing interest after a few weeks then I should move on, but for me it's only been a few days so I'm in a grey zone. I understand it takes time to build attraction.

So tell me, is there a specific amount of time you should try before giving up? Or is everyone different?

Thanks
