What I mean by "work" is that all persons in the "R" are generally pleased, feel cared for, feel that they have adequate time, sex etc... with the other(s). This is where these R's fail - someone always ends up "odd person out". Most people don't cope with that well.
I'm not talking about pleasing yourself to the exclusion of pleasing others. By pleasing yourself I'm just referencing acting in a way that is authentic for you. I'm just talking about letting go of the anxiety associated with pleasing others. IMO - if you are dating more than one person then odds are good that someone is happy with you and themselves even if someone else is not. In this kind of arrangement it is easier to say, "Gee, I'm sorry you feel that way, take some time and when or if you feel better give me a ring."
LFL asks a worthy question. What about love - is it too scary for you right now?
