I think a lot of people get caught up in what "successful" means when they ask these kind of questions. If you mean happy as in long term, glued at the hip, closed in a triad or quad, all of which seems to be the "poly dream" for those starting out (at least in these here parts), then yes, extremely rare. Some people really feel successful and happy in solo poly relatuonships where they have loving and spritual connecting moments in one night stands or with their friends (where everything is consentual amongst many). Its all subjective and the vagueness is awesome I think. Love poly vagueness when it comes to success. Love that nothing is pinned down. "Happiness" is accomplished by individuals deciding to be so anyway in my opnion anyway.
