How do u know if a girl is playing hard to get or is just not into u?!?

the best way is to ask her

Well, if she often makes a smug little smile when she's around you that's a sign she's playing hard to get. Also, if it seems likes she's playing games with you, that's another sign, and so is if she always says that she has lots of stuff on her schedule but can almost always squeeze you in. When you give her your phone number, does she always wait a few days before calling. If it is starting to get on your nerves, text her saying that you don't like people who play games and then stop texting her until she comes to talk to you. Make sure that it is a text, not in person. If she actually likes you, she will come and talk to you.
