We’d like to hear from people who are in a throuple or who used to be in one, and what their relationship was like

The Guardian’s Saturday magazine is looking for throuples to talk honestly about the experience of love and commitment. We’re particularly interested in talking to throuples living together under one roof, as well as throuples who are raising children as a unit of three parents. Is it easier to manage childcare duties when there are more adults in the room? Or more difficult?

It is important that all parties agree to being featured. This means we need you to ask the other people involved whether they’re also willing to take part.

We are hoping to feature existing throuples who are happily cohabiting, and also throuples who have broken up, and are willing to be candid about why they didn’t make it. The idea is to spotlight alternative ways of living and loving, and explore how we can reimagine the family unit.
