What does it mean when a girl slows in talking when you come near?

either she wants you but won't do anything about it coz she has a boyfriend or she's telling people you're into her but you're not her type. whatever it is, just ignore her coz she's got a dude anyways so you probably have only a 1% chance of tappin that ***, specially since she cancelled already before. if you really want her though try chatting her up first in the gym then move on to coffee or something before going full out on a real date
