If two persons live together but one of them are married or in a registered partnership elsewhere, they are not considered a cohabitation couple. If friends (without being a couple) share a residence, they also are not considered a cohabitation couple. If a couple lives on different locations, they also are not a cohabitation couple. As long as the intention not is to live together, they also are not considered as a cohabitation couple. A cohabitation couple relationship remains on the other hand if any of them is away on a longer journey, temporarily works at a different location, is hospitalized etc. as long as the intention was not to move apart.
