Ok I first started talking to this girl from plenty of fish and got her number after my third message.
I texted her 24 hours after that. This entire text convo lasted about 30 min.
Me: Hey is this (her POF name)?
Her: Haha..yep it sure is..who's this?
Me: Are you able to guess which guy this is

?
Her: Nope
Me:

not the slightest clue?
Me: Ok well ill give you a hint, it starts with a c and we talked online.
Her: Chris?
Me Nah, got the first two letters though, take one more guess then i'll tell you

Her: Chase?
Me: Nope. Minus points for you

My name is Charlie but I'm (my POF name) online. And you?
Her: Well mine is in my profile so now you can play this game sucker

Me: Fine be that way

Well I just wanted to make contact and make sure you were real. I can't talk tonight since I have a lot to do before class tomorrow but i'll call you around this time tomorrow if you behave

Her: Haha...ok sounds good. Have a good night.
however I called her 24 hours later and she didn't answer. I didn't leave a message. What should I do? Wait a day? send a text in a day?
How about something like:
"Will you get cold feet again if I call you?

" Then calling her immediately after she texts back (assuming it's a flirty text) since i know she's near her phone. If she doesn't respond to the text or pick up the phone I'm done with her.
Or something along those lines. Any better ideas? I don't mind waiting a bit but I don't want to leave it at that after just one call attempt but I don't want to sound needy/desperate either.
I say one more text wouldn't hurt, if she doesn't respond to that then it's certain. Right now there's just so much uncertainty. And no unfortunately I don't have any other girl options. I wish I did and I'm working on that
