If she liked you she'd probably ask you out straight up, girls don't normally like to confuse guys or play games with them they are normally quite upfront about things and aren't emotionally unstable at all.
The girls you date have bigger testicles than the ones I date apparently.
That's like saying all guys wanna ram their rooster down the nearest hole as fast as possible, then leve whatever remaining relationship there is.
My ex did the exact same thing this girl is doing to OP.
op, ask a close friend, and odds are they'll ask her friends. If she finds out, she'll be expecting it, and she'll be really cautious around you so as not to ruin it. If she doesn't like you after all, she'll avoid you until the news dies down.
