i have a crush on my best friends younger brother

i (16f) have a crush on my friend annie’s (16f) younger brother chris (14m). i feel terrible about this, but im SO into him. more than i have been with any guy in a long time. ive talked to annie about it and she tells me not to make a move, but i cant help myself. when i know im going to see him i wear something really low cut and a push-up bra. when i talk to him i look deep into his eyes. i flirt with him. hes such a funny and nice and complicated person ughhh. i cant tell if hes into me
