We're in a day and age where you can have your cake and eat it too, they're called open relationships. You know what's not fair though? Having one without your fucking SO/spouse being knowledgeable about it. Like I said having an affair or constantly cheating makes someone a terrible person as you're literally shitting on the person who's supposed to trust you most. If you don't want to only screw one person, don't get married with that on the table. God forbid people just be honest with their spouse or more importantly themselves, and not "settle down" when they have no real intention to. Epitome of selfish.
