And regardless of whether friends turn into starry-eyed lovers, in general, FWBRs tend to mirror the level of closeness found in romantic relationships—suggesting the greatest difference between a romantic partner and a “friend with benefits” might be what we call them.
This is the tricky thing about friends with benefits: They’re hard to study and even harder to define.
"Find out exactly what you're really saying yes to," says Meyers. Keep hugging, kissing, and cuddling — especially in public — to a minimum, Meyers advises: "You have to stay detached or it's going to become a romantic relationship, which changes all the rules." You can also keep boundaries in place by not leaving stuff like toothbrushes and clothes at each other's places.
The more specific you are about setting guidelines — How often are you going to see each other? Yes, you two are friends, meaning — presumably — that you get along and have a good time together. But think twice before making your FWB your date to your college BFF’s wedding or inviting them to dinner with your parents.
But though the demise of an FWBR might look similar to that of a romantic relationship, the interpersonal and psychological implications of being friends with benefits belong in a category all their own (maybe).
