how am i supposed to move on

so my guy best friend of three years got a girlfriend ive always kind of had a thing for him but bad timing, he was talking to someone before her and they stopped and i was gonna tell him i liked him but she did first. i eventually did and he didn’t feel the same but we’re still best friends. we talk all the time still and he’s so sweet idk how to move on i kind of want to wait because i think he’s worth it but idk how long that will be. he gets me so well and he can make my day 100x better immediately.
