Relationship escalator
The culturally prescribed trajectory that monogamous relationships are expected to follow — date, exclusive, move in, marry, parent, stay forever — treated as the natural shape rather than one option among many.
The relationship escalator is a term popularised by writer Amy Gahran in her 2017 book of the same name. It names the implicit script that Western culture provides for romantic relationships: meet, date, become exclusive, present as a couple, move in together, get engaged, marry, buy property together, have children, stay together for life. Each step is expected to follow the previous one, and a relationship's progress is measured by how far up the escalator it has travelled.
Naming the escalator makes it visible as a script rather than a natural law. Relationships that don't follow it — long-term partnerships that don't cohabit, deep commitments that don't marry, couples who don't escalate to children, partners who stay non-exclusive — are evaluated against the escalator as if they were failing to progress, rather than as relationships that have chosen their own shape.
Ethical non-monogamy and relationship anarchy both reject the escalator as the default. Polyamory tends to refuse the single-pair shape that the escalator presumes. Solo polyamory refuses the move-in-together rung. Relationship anarchy refuses the whole frame, treating each relationship's shape as a question to be answered rather than a default to be inherited.
The escalator concept is useful even for monogamous adults thinking about what they want. A great deal of relational unhappiness traces to people having followed escalator steps without examining whether they wanted what each step entailed. The point of the term is not to dismiss the escalator's stops — many people genuinely want them — but to make the choosing visible.
