According to hit performer Herb Alpert, this song was originally written as "This Girl's in Love with You" and he requested Hal David to adjust the lyrics for a male focus. True or not, a few lines (and the title) were indeed slightly rewritten for what became Alpert's hit version. From "That Guy's in Love", a characteristic Hal David epic of suspicion, anxiety and misery, sung few months earlier by Danny Williams, to nothing more than a lovesong (sung by Herb himself in devotion to his then-wife Sharon).
