Girls!! Please help!!?

Well I've been talking to this girl for a couple of days( texting mainly) and we've tried to set up a date a couple times... Example: she said she wanted me to come over and hang at her house.. I said alright what time? She just says idkk. And then nothin ever happens... Why is she doing this? By the way, we haven't met in person. Please help! Im startin to think she doesn't like me...
