I was completely obsessed by a song I used to listen a couple of years ago (I have completely forgotten the name of it and it is driving me crazy!!). The genre of the song is house, something similar to Armin Van Buuren's style, it's from 2-3 years ago if I'm not mistaking and the lyrics are sang by a woman. The only thing I remember from it is this line: "You are not the man I... (thought? knew?) Unfortunately that's all I remember. I would really appreciate if someone could help me with it. I keep on searching for it for more than a month.

Thanks in advance
