I need help on finding a song?

The chorus goes like this: If your leaving me babe, I don't wanna know...I don't wanna know. If your done with me babe, I don't wanna know....I don't wanna know.
If you can tell me the artist and the title of the song I would really appreciate it. I have been searching every where for it. Thanks for the help.

Taio Cruz - I just wanna know.

I think that's what you're looking for.
