im done but i still want to try

i feel really done and i've been constantly asking my friend for advice because of him or i always asks what she thinks. we both really like each other, well now i think he has lost feelings, i don't know if i should still try or just leave it. Last night we were just hanging out and with other people. He was flirting alot lastnight and but now he left me on open i dont know if i should still talk to him and clarify if he still likes me, he never leaves me on open. :( i feel really sad about this cause i really like the guy and he did care he gave me like everything but we weren't dating.
