Would this mean this girl i just met isn't interested, or playing hard to get?

I met this girl in class yesterday and i got her number. after class i txtd her and she txted: "I'm gonna go to bed. I'll talk to you later"... if a girl liked u wouldnt she at least make time to talk with you? (im in college btw). She seemed to laugh at a lot of what i said, even tho it wasn't that funny .

btw this was right after class,(4pm ish)

she probably thinks you are too desperate..girls LOVE it when guys are a chase..its fine if you like her..why don't you NOT text her for one day and see if she initiates a text...then you'll know she is interested..trust me..

girls play hard to get..because they know you will want them more..
don't let her play the game.. let her chase you!!!

Are you sure you're in college?

Geez, just because she was tired and wanted sleep you need some sort of explanation?
