What song has a man rapping and a girl singing?!

There's this song that I know I like, but I can't remember the lyrics or the title!. I don't even remember the artist!. But I know that there's a man rapping and a lady sings the chorus!. I think it's about how a partner ignores someone, and they're not going to sit around waiting for them to call anymore!. The music video has a man (I think he may be white) in an apartment, standing in the kitchen, rapping, and then a woman who sits on the bed when she sings!.Www@Enter-QA@Com
