Re: Hb said she's only interested in talking?
You could be dealing with a firefly bro, a girl who is always just attracted to the next biggest brightest thing. As far as advice on how to get her I can't help you.
To me it seems she is just using you for validation and someone to talk to, you are someone she won't miss until you are gone. I have a few girls like this I chat with every now and then, but I usually just ignore them as they are just wanting an ego boost or to feel better by talking to me.
Aside from that, I find these types of girls tend to be generally a waste of my time as they are shallow and can't offer me any mental stimulation, but to each their own.
Girls like this will start messaging you once you ignore them, but once you message them back its almost immediately game over. Next time you think of texting her, go out and get some new numbers, if you happen to see her in person smile and wave then just keep going. She may care that you are just ignoring her but chances are she won't, right now she has you right where she wants you, but like T-Mal said there isn't enough attraction there to keep things going, and unless you can see her in person there is little chance of building it back up.
There is my synopsys and should be a bit more about what you are looking for.
