Umm, oh their like on the tip of my tongue. The first one I can think of that reminds me of that is I look so good without you~by~...was it lady antibellum? And the second one is from Kelly Clarkson... Since u been gone. (or maybe it was called "behind these hazel eyes") Hope I've helped =)
I don't know about a song like that, but this is a good song. At least it is for bad break ups. Its how a lot of people feel after the break up.
Idk about the type of song you are looking for but Butch Walker the best thing you never had that is a great song
I was thinking there must be a million of them...LOL
