How can I tell if he likes me?

maybe he's just testing if you feels the same way. the "other girl" thing perhaps is just a thing to make you jealous of. and the thing that he turnds around when you're around, perhaps it's just another move to get your attention. that's just what i think. i mean, if he doesn't even look in your eyes or just say hi/hello. idk. it's...."no more"
