Can anyone tell me the name or artist of this song????

Im trying to find a song i heard on the radio. please help. its a mix between opera and i think house??

i only have a few lines of the lyrics. they are:

"i'll leave you forever and everything"

"time to go"

"my heart is broken"

"im gonna let you go" (or "im going to let you go")

i know its vague but i need to know what this song is called. like i said its a mix. one woman is singing in a sort of trance or house genre. it may even be hip hop. and another woman does the chorus with her but in an opera style. the song is kind of a love song. like a woman singing about a broke heart. but its the kind of song you can dance to.

ANY HELP WOULD BE AMAZING. THANK YOU!
