I've been there too with some girls. I think some of them have this thing about not wanting to initiate with the guy first because they think it's gonna make them look desperate or needy or whatever, or that it's a sign of weakness for them as women to show how much they're into you. So they would rather you do it. Some even have the attitude that all they need to do is just sit back and wait whenever they want to have a convo with a guy, that you'll always want to.
Well one reason is that many women are put under the impression that men don't like to communicate , especially through texting or on the phone. We are made to think that guys find too much messaging and texting to be annoying so we don't want to be a bother/turn him off and would rather wait until the guy texts us to show that he is open to talk.
I personally dont like texting guys in the beginning for example. I told a guy we would set something up later in the week (we were both kind of busy) and I will wait unt e texts me. It shows me he is interested
