Have a listen to Secret Separation by The Fixx. Actually, have a listen, because the video didn’t age well.
Imagine your soul mate, your one true love, your reason for being - and you must giver her/him up because you are both committed to someone else. You must sacrifice your happiness, and with it your true love’s happiness. Talk about sad songs! Heartbreaking lyrics, and, given we’re talking 1984, the music fits them perfectly.
Close your eyes, though, or you might not take the song seriously. The video producers didn’t seem to.
