Feelings hurt by a guy I like?

this guy I like was staring at me at cracker barrel(where he works) and I pointed it out cuz he called me a creeper so I was sticking up for myself and he said why would I stare at you, you have nothing I want and something like **** you and I almost cried. I don't have big boobs and I'm 5"2 and 15. I don't know why he was so mean so I unfriended him from facebook and sent him a message by the power vestedd in me you are now defriended and blocker you may now kiss my butt. why was he so hurtful I don't understand he was looking and smiling at me so wtf!!!!!!!!!!!
