What do i do when a respected friends tells me she like the boy i love?

OMG! his my ex. but i am so in love with him and he love me to as he say...All he wants is for me to change my attitude because it gets nasty at times.But i feel like a we will never be together because obstacles are always placed in between us and this has severly broken my heart to know that should could possible love him.The twist is we are all friends and i know they will be together hanging and feelings will grow stronger
