Why does she do that?

[Anonymous]

So she’ll talk to another guy in front of me and look at me while doing so. But when she sees I’m not paying attention, she walks away. Why?

If you rejected her - she is trying to show you in a childish way that she can do better (like a revenge).
If you never been together she is trying to flirt but you probably ignoring her for a while now.
If you dated before maybe she wants to show you that she is over you…
Just my guesses 😊
In any case, this is not a nice way to get someone’s attention.

could be she's trying to gain your attantion

or you creep her and she try to get rid of you

Lots of missing context here 😅

Probably because she’s a cunt so start talking to other girls & be a dick in return.

Making you jealous. Talk to her and if you like her THEN ask her out. She is ready.
