What do i do? does he feel the same?

im 15 and Theres this guy in my school that i have recently realized i have feelings for. In the beginning i tried hooking him up with one of my friends and it didnt workk for them and from there i fell for him. We use to sit together at Lunch and we flirted constantlly and we both ended up movin on in seperate relationships. I noticed that the flirting subsided but always had feelings for him. Now were both currently single and hes been flirting with me again : for instance when i walk p him he bumps into me or wont let me p and has an amazing smile. Idk what to take from it Does he like me? or is he just goofin arround? i dont even know if he does it with other people i just need advice thanks.
