[Verse 1: John Mayer] I was born in the arms of imaginary friends Free to roam, made a home out of everywhere I've been Then you come crashing in, like the realest thing Trying my best to understand all that your love can bring [Chorus 1: John Mayer & Taylor Swift] Oh half of my heart's got a grip on the situation Half of my heart takes time Half of my heart's got a right mind to tell you That I can't keep loving you (can't keep loving you) Oh, with half of my heart [Verse 2: John Mayer] I was made to believe I'd never love somebody else Made a plan, stay the man who can only love himself Lonely was the song I sang, until the day you came Showing me another way and all that my love can bring [Chorus 1: John Mayer & Taylor Swift] Oh half of my heart's got a grip on the situation Half of my heart takes time Half of my heart's got a right mind to tell you That I can't keep loving you (can't keep loving you) Oh, with half of my heart [Verse 3: John Mayer] Your faith is strong But I can only fall short for so long Down the road, later on You will hate that I never gave more to you than half of my heart But I can't stop loving you [Backup Vocals: Taylor Swift] I can't stop loving you But I can't stop loving you with half of my Half of my heart Half of my heart [Chorus 2: John Mayer & Taylor Swift] Half of my heart's got a real cool imagination Half of my heart's got you Half of my heart's got the right mind to tell you Half of my heart won't do [Outro: John Mayer ] Half of my heart is a shotgun wedding to a bride with a paper ring And half of my heart is the part of a man who's never truly loved anything Half of my heart Half of my heart Half of my heart Half of my heart Half of my heart Half of my heart
