Songs about being in a relationship where you were constantly lied too?

[madison]

I was in a year long relationship,he told me all this sweet love stuff and then we broke up because we were going thru a difficult time and then 3 weeks later he was dateing the girl who was a reason we broke up because I was constantly told how much they flirted and stuff, and now he's tellin her litteraly the exact long love messages but substituting my name for hers. (She posted there messages on a social media site) Is there any songs about just like being lied to in a relationship? Or like any really good breakup songs anybody knows of? Any genre, thanks in advance!
