There's a Taylor Swift song for that.

                     Love Story - You and him like each other but you aren’t allowed to date

The Way I Loved You - You love your new boyfriend, but you can’t get over how things were with your old one
Invisible - You like him but he likes her, and she’ll never like him, and you do
Fifteen - You believed everything he said, and now you realize that young love doesn’t last
Should’ve Said No - He cheated on you, and she was not worth it, and he’ll never have you back
A Place In This World - You just want to fit in
Forever & Always - You and him went from being perfect to horrible so quickly
Tell Me Why - If he loves you then why does he like to hurt you?
I’m Only Me When I’m With You - He’s the only person you can be yourself around
Teardrops on My Guitar -You want him so bad, but he only sees you as the girl he talks about his girlfriend with
Mary’s Song- Our love is everlasting
Today Was A Fairytale- That was the best date of your life
Fearless - With him, you’re not afraid to do anything
 White Horse - He broke your heart, and you won’t forgive him
The Outside - You don’t fit in in his world
Jump Then Fall - You fell for him, now he just needs to fall for you?
 You Belong With Me - You’re so much better for him than she is
