A heart can only be mended by a friend

I should have listened to them when they said he was playing me
But instead I just pretended we were meant to be
I really loved him and I thought he loved me too
But I should have listened to my friends for they truly knew

I really should have listened but pretended I didn't hear
Now all I'm doing is fighting back the tears
I'm sorry I didn't listen but the only way a heart can mend
Is if its mended by a friend
