Cover art for Gone lyrics by Kelly Clarkson

I think that 'What you see is not what you get' is a line stating that maybe he thought that he could take advantage of her, and lured her to be his girlfriend. He realized that she wasn't weak and that she wasn't worth even trying so he broke up with her. She pushed him away alot even though he 'tried' to make up for it. He kind of fauxed his way in the breakup so she wouldn't realize it...

Toodles.
