its from "You're so last summer" by "Taking Back Sunday"

i broke up with my girl friend and this was on her profile... i still care about her and want to know what shes saying

the song is about a girl leaving a boy which is oppisite from our situation so reverse the song alittle

Answer 1

Its saying that if you are saying she is bad news then you are a liar.

Maybe talking bad about her to your friends. And leaving her, hurt her so she probably thinks everything you ever told her was a lie.

if you love her then maybe you shouldnt have left her.

Answer 2

I think it goes back to ...In some relationships when things start to fall apart your opion of your partner may change. Leaving only negative opinions and views of this person when in fact in your mind you have formed these views to help you move on to get over that person. But this may not be how the person really is or how they really feel.That person may be reaching out trying to get you to see the real them again but out of your anger or hurt you can only see the image you have formed in your mind.
