Seem to be really common now but is it just me that doesn’t get them? Usually it tends to be with someone the person has met online (think tinder etc) so no actual friendship just sleeping with each other occasionally and calling it a FWB surely there needs to be an actual Friendship first to be a Fwb? Then it ends up with one person getting feelings (normally the woman yes I know men do too but let’s face it it’s mainly the woman) aibu to not understand “FWB” being used for someone you have no friendship with and think most of these situations end in someone getting hurt?
