Most Helpful Girl
I think part of it is their way of flirting with you; they might not know any other way to flirt. They probably don't think what they're doing is annoying (even though I find those things annoying, myself). I can't say it's that way for why they don't call you; I have no explanation for that. When I like a guy, and it's obvious he likes me, I waste no time with games. If he calls me, I answer the call. If I say I'm going to call him, I call him. It's useless to play games when something is already established between the two of us. If she's trying to gauge how much you mean to her, it's probably because you're not showing it or saying it.
