So basically everyone would expect their partner to not go, just because you can't? That's ridiculous. Romantic vacation for the couples doesn't mean it has to be for other people. I would never make them feel guilty or bad for going, because I'm not a child and I'm not insecure in my relationship. Would I be bummed to miss out on a trip when I love to travel? Of course. Would I go on Reddit so 9/10 comments can tell me "well your partner must be cheating or wants to hook up with strangers" probably not. Maybe this is Karma for getting a couple kicked out of their apartment because you just assumed their dog was evil (breed discrimination by the way, I'm a Rottie Mom and that makes me sick) because he gasp liked to run down the hallway!
