"She's secretly dating more than one guy"?!!!! Help please I'm freaking out?

[TraySean]

She's 17(very smart, history buffed girl,very nice and never parties) I basically like this girl so much in a way that I haven't felt before from past relationships. We have so much in common( same birthday which I think is pretty weird in a good way). We had our first date about a week ago. Went bowling and talked all night till about 2 am so had to drop her home. We talked a little bit about relationship and it seemed like she's very into me and she said she's ready to have a relationship again.
We're going to a second date this week depending when she's not busy. She told me once that she's very trustworthy which I believe. And she told me over text that "I've been in her mind a lot and wants to hang out again soon" so it seemed like she really likes me. For the sake of it, I made a fake facebook account and basically messaged her that I've had a crush on her since grade now. And like she is, she took it in a nice way and offered to just reveal who I was.. And I asked her if she was seeing someone atm or even dating someone and I was shocked on her reply, saying "no one actually"..

She always message me first. She seemed like she's very into me but why would she lie about seeing someone over a fake account? Does this mean she's secretly dating some other guys ?
She gave me an impression that she wants me and now I'm all pissed off to myself of even making a fake account to just make myself mad. Why do you think she lied?

Two things could come out of this : she either said that you were on her mind a lot and you should hang out again because she may not actually feel the same way about you as you feel about her and wants to tallk to you about it because she didn't actually state that she wanted to see you as in a date again or she could mean the complete opposite that she does like you and does want to see you again.
It she could be a complete bitch who date more than one guy . And you will need to confront her about this . Or maybe before you confront her about it get more evidence: look at her face book friends find any guys that you don't know or she seems to be good friends with and talk to them see what they say. Or just confront her with what you already know.

Technically she didn't lie. She's single and therefore anybody is fair game. She might really like you, but since yall dont go out she has the right to tlk/flirt with anybody she want. But, just start texting her good morning/night txts and friendly stuff. Next time yall hang out let her know you really like her. Kiss her...either way, good luck

She doesn't sound like she's trustworthy at all. I'd confront her with what you Already know before you get with her and end up heartbroken further down the line dude!
