Mirroring the others preferred type of communication?

[xRJ85x]

Sorta a lesser detail in the dating world, but possibly an important one nonetheless? I know most people agree calling is the way dates should be planned/changed/canceled/etc. However, most is not all, and while I'm not even sure "most" is the proper amount in this day and age, there are at least some out there who don't care or even prefer a specific medium of communication (what I'm getting at specifically is texting). So do you think it's best to sort of mirror the way the other person appears to prefer to initiate contact with you?

 

I ask this because this girl I met online who I've been trying to arrange a date so far has initiated contact only through text msg. I called her once and left a message, got a text back later telling me she was sorry she was busy but still wants to go out. So I called her again, and we scheduled a date on the phone. We'll she ended up having to cancel (fairly legit reason too), but she again texted me saying how sorry she was and that she wanted to reschedule. So my question is, do I call to confirm the reschedule? Do I text her saying "no problem, I'll call you later to reschedule"? Or do I just reschedule through text.

 

Obviously, this all seems kinda stupid worrying about it but I do because A) I'm really laid back and really don't care how anyone wants to plan a date. I only call because it's "how it should be done." and B) Because there's no doubt a phone call holds much more weight than a text message, so I don't want to give off the notorious "desperate/chasing too hard" vibe that women love oh so much. It's a problem because I haven't even gotten the chance to meet this girl in person. Thoughts would be greatly appreciated.
