When do you know is time to stop pursuing a girl?

When she's calling the police, it's time to stop ;p

But I'm skeptical about the idea that girls "like" to be chased.

I mean, sure, they'll like to be chase because they'll feel powerful, like they have the person right in the palm of their hand, but whether they'll "like" it in a romantic and sexual partner-way? I really don't know... I certainly haven't heard it from ANY girl I've known...

I mean... Everytime girls are being chased they just tell me that they find it "scary" or "weird", "pushy" or "needy", and they don't think that's cool, mate... I mean... sometimes even call them "creepy stalker-guy"... Imagine that!

A better thing you could do is to make HER want YOU so much, SHE'LL CHASE YOU...

Anyhow, this is not really answering your REAL question, isn't it?

So... How do you know whether a girl wants you to stop or not? If she seems GENUINELY disinterested, which you can notice through her answers (are they short? not detailed?), her bodylanguage (does she signal that she wants to go away, if she's looking at other things), and her tone of voice (with no energy at all, just dull), then STOP.

If she is flirting with you or is genuinely INTERESTED in you, on the other hand, then continue and go out with her already!

I hope you've learnt something of value through this post, even though it's so general (some details would've been nice)...

Good luck, anyways, and have a great day! ^^
