How do I confess? / Should I?

Need suggestions how to or if i should confess to my crush who also sees me as a bestfriend.. for a little background, me and him have been friends for over 3 years now, at first I saw him as a friend and/or brother. idrk how to explain how i fell for him lmao hes not really conventionally attractive but idrc for looks. He is smart, humorous, and i can really relay on him when needed. ive given him hints that i like him but, idk if he catched on...  he gives me mixed signals which are STRESSING ME OUTTTT, if i do confess im worried that he'd reject me even though im not really interested in him romantically. At the end i just hope he reciprocates the feelings!

HOPE YOU CAN GIVE ME TIPS!! <33
