A friend of ours likes to say these stresses aren't poly problems; they're roommate problems. We don't tend to consider live-in romantic partners the same way we think about roommates, but a lot of unnecessary suffering can be avoided when we employ the same strategies as for non-romantic roommates—strategies like negotiation and clear expectations around dishes in the sink, household chores, basic courtesy, respect for other people's sleeping schedules, and willingness to clean up after ourselves.
