Parallel polyamory

Parallel polyamory describes a network in which each relationship has its own private context and the relationships are kept separate from each other socially. Partners know in principle that other partners exist; they typically know names and a general outline; they do not meet, do not share friend groups, do not share holidays. The metaphor is parallel lines that never cross.

Parallel polyamory often emerges by preference rather than by design. Many polycules naturally settle into parallel shapes because the people involved value relational privacy, lead full lives that do not need additional social integration, or simply do not find that their metamours would be friends absent the polycule connection. The structure can be deliberately chosen too — some practitioners explicitly prefer it from the start.

Parallel poly is sometimes confused with don't-ask-don't-tell (DADT), but the two are different. In parallel poly, partners know about each other; the information channel is open. In DADT, partners don't share information about outside connections at all; the information channel is closed. Parallel poly is about social separation, not informational opacity.

Parallel structures simplify the network logistics. Less metamour coordination, no group conflicts, full relational privacy for each pair. The trade-off is the absence of the network-as-support that kitchen-table arrangements provide — no built-in mutual aid, no community for the kids if children are part of the structure, more compartmentalisation costs for the person at the centre of multiple relationships.
