Youre learning the most valuable and important life lesson here in that most of the male population are pigs., and it sounds like he's no different. Boys are usually interested in girls for one thing only and will take to who will most likely give them what they want, but don't be upset here as there are millions of boys in the world and don't be in any rush to have a BF as you have a whole life ahead of you.
So if he wants to play his little boyish games here, just move on and find someone better. Good luck
