If anyone needs explanation why it's not good for anyone to not only have inter-gender competition while looking for a mate, but basically forever... well, there is no helping retards.
They always try to downplay jealousy, but kinda admit to it when asked. It's unhealthy to fight for someone's attention at all times. Just like it is to force multiple unrelated adult men/women to live together and act like they are a family, basically a set of siblings or a children's camp. It's not even like roommates, because they are expected commitment to the well-being of the "unit".
