<human>: To start out, I'm a 29 year old man, she's a 32 year old woman. Met on a dating site, exchange some emails, then began talking over the phone. We met up in person, and (I think) we're hitting it off decently; before we left she mentioned that she wanted to see me again, and I responded likewise. 

However, whenever we have a phone conversation, it's me calling her, never the other way around. This concerns me. I'm pretty sure that we're going to have a second date(we've talked via phone since the last one), but after that, it's up in the air.

Normally I can read between the lines when a woman isn't interested in me, but this is a tough situation; by all other signs she likes me and wants to at least meet up again, but I worry that since she's never given me a phone call(and she does know my number). In case it isn't clear, I'm quite interested in her.

Other details:

* We're both professional, college educated adults (in different professions, if that matters).

* We live 60 miles apart, hence why we've only met up once so far.

* We're both kinda intellectual; we found common ground right away as fans of A Song of Ice and Fire by George R.R. Martin.

* I'm a somewhat awkward person, conversationally.

Could you distill the essence of the text into 1-3 sentences?
<bot>: A woman I've chatted with always waits for me to call her rather than vice a versa. Does that mean she's just not that into me?
