One day I asked what someone’s relationship status was, and they said “I have a girlfriend but she’s been missing and is presumed dead, so I don’t know if getting another GF would be cheating”. It’s at that moment when I realized how complicated relationship statuses can get. Like that Seinfeld episode where the guy is in a coma so he lends his girlfriend to another guy.
Star Trek Enterprise episode where the polyamorous Dr. Phlox introduces his wife Feezal to Trip, she makes him uncomfortable by aggressively flirting with him in front of her husband.
