From my understanding, a Situationship is more than just an FWB because in this situation they want all of the benefits a exclusive relationship would bring just without the commitment part and the labels. They dont see each other as friends but they also are holding back from it being a real relationship
Situationship implies either both of you aren’t sure what you’re looking for or one of you wants more but the other doesn’t/isn’t sure so you’re doing something less committed as a compromise. A FWB implies the only thing you want from each other is sex without the confusion of if either of you want more or doesn’t quite know what they’re looking for. One can lead to the other and there’s some overlap but they aren’t the same.
