It's common to see what we call Schrödinger relationships:* relationships that are near-over in practice, but have fallen into a pattern of comfortable non-contact or non-intimacy. It's easy for poly people to let such non-relationships linger a long time, because when you have multiple partners, there's often no incentive to formally end a relationship in order to "move on"—and it can feel easier to drift apart than to have a tough conversation.
