Does he like me? Confused :/?

okey i have a big problem. I'm 15 years old and I like a guy who is 16 years old..I don't know if he likes me back but we talk on fb sometimes and he looks at me in the school brakes..I think he likes me but I'm not sure..this guy has a best friend who is 17 years old..he told me on fb that he likes me and yesterday we go out together and with an other friend of him..we had fun...He phones to the 16 yeard old guy that i like but he couldn;t come with us...So, the problem is..DO I like them both? Does they like me????SO confused=///
