what a fool

this is just a typical type of story, a fool and a cheater. the problem is i am the fool. one night at october i confessed my love to her. i tell her how i feel and she doesn't have to do anything for me because i just want her to know how i feel. she tells me she likes me but she's not ready for a relationship. i said i'll wait and it's fine if she chooses to leave me. months after that we always talked and i know there's something between us because she said "i wanna be with you, let's start dating" but as a joke. and she did that 2 times. i let it go, i thought she's just confused. i found out that she's dating another boy. i confronted her and she denies everything and tells me to stop waiting for her. i didn't reply but up until now i do wanna ask her if there's a problem with me?
