Most Helpful Guy
Try not falling all over yourself for one guy- you're young, you should be dating a few guys and not let any of them take over your heart. Have your own life and stop depending on the reactions of some guy to make you feel complete. You're really pretty- you should have your choice of men in your game and if they call you a player, say you are your own person and make your own choices, then cut them out of your life. Take charge, do your thing.
You're letting him play the field and flirt and getting upset, well, you're the girl you should be doing that with men. You select the man, not put all your eggs in one basket like you got no game. Find like five guys you like and give them attention only when they treat you like a princess.
Completely ignore this guy for a week or 2, he will be eating out of your hand. He is just in it for the pursuit, he probably want's to test what kind of girls he can "get" and he already has you conquered.
You're so pretty, in a few years you'll know how to have any guy and will have your pick. Just relax :D
