Does this guy like me, or is he just a flirt?

Hey guys, I could really use your help! So theres this guy from my grade, we really had no interaction until a few of months ago when he started saying hello. Im unbelievably shy and considering he is confident and reaaally good looking I kind of mumbled back to him trying not to blush, and thenone day he cornered me and started up a convo. Since then everyday before homeroom he would come fine me and chat, it didn’t matter where I was at school, he would find me and we’d always have big smiles on our faces and laugh alot, we seemd to have heaps in common. sometimes he would be walking a certain direction, then if he saw me he would stop uturn and come over to me, or call out to me and compliment on things like my hair, or my outfit. he added me on fb and we chatted abit, and he said we shoul go out for coffee sometime.So I was starting to think that maybe this guy likes me but just when I started thinking this, I also started to notice that at lunch time, he had one on one flirty convos with other girls, and when we had school party (which he told me I should go to so we couldhang out) he spent the whole night surrouded by a group of girls and was openly flirting with them and we never talked once?? I was peeved so I started flirting with some other guys from school, when we got back to school he told me to stay away from those guys and they arent good enough for me.. and now when he walks past me he doesn’t even look at me or say anything.. im so confused now! he was the one flirting with other girls first? any input would be great cause we still aren’t speaking!
