Presumably he left when Relm's mother (his wife or lover, he had to have done her at least once) died, or perhaps only after he'd had sex with her. That's up for grabs, but it's probably the former since Interceptor is cool with Relm.
Actually, the source of confusion come from the cave where you rescue either Shadow or Relm. If you waited for Shadow on the Floating Continent, he will be there instead of Relm. The problem is, nobody bothered to make the dialogue between your characters any different depending on the situation. So when you rescue Shadow, your characters will refer to him as "she" and "her," because the game is using the dialogue provided my the case that you're rescuing Relm.
