Who did this song and what was it called? "Are you laughing now? Cos I'm not. And I miss you".?

These are the only words I remember. It was definately a bloke singing and it is not a recent song. I think it might be a decade or more old, though someone may have sang it on one of those X Factor type shows a couple of years back. It's not a rude song, just a love song about a guy missing the funloving woman he used to know. He may have sang about their walks by the lake and how she was never serious about things...
