Six months of Guardian interviews with people in current and former throuples repeatedly expose a structural advantage for an established pair, which may retain marriage, housing, family routines, money, schedules or veto power while asking a third person to enter on unequal terms, an advantage that can persist even when all three describe the bond as loving. [1]

Lucy describes living in a married couple's home under allotted dating days and a wife's unilateral veto, while Caitlin says a couple in Marseille could cancel on her for private time and ultimately treated her as an accessory rather than an equal partner. [1]

The feature also reports a durable counterexample in Rachael, Aaron and Kasey, who use separate one-on-one time, a trust naming Kasey as a beneficiary and medical powers of attorney, practical arrangements that they credit without proving a universal formula. [1]

No qualifying pre-cutoff X status was verified, and message-board terms, films or confessional memoirs cannot establish prevalence, generational change, legal protection or a typical outcome for three-person relationships.

The recurring hierarchy is therefore a question raised by several testimonies, not a population finding: readers can look for who controls home, time, money, exit and legal standing without concluding that every throuple exploits a third or that any relationship form guarantees equality, while broader conclusions require representative research with clear legal and clinical measures.
