Girls have their own way of letting a guy know she's into them.

Does she ask you many questions about yourself?

Has she ever asked if you were single or if you were dating someone?

Does she make excuses or reasons for her to be near or follow you around?

Does she frequently look your way or find ways to grab your attention?

And a really big indicator: Does she get handsy with you, squeezes your muscles, or rub your shoulders?

If you said no to all of these questions then maybe she's not that into you but honestly you could never really know unless you shoot your shot and ask her. Be careful though because some girls think it's really weird to be hanging around guys that have a crush on them and they're not interested.
