I've known plenty of poly relationships that that have managed with poor communication , self awareness and low levels of trust. They suck, but they do exist and manage to "get away with it". Just like a mono relationship can suck with poor communication, self awareness and low levels of trust and still manage to "get away with it". The same dynamics are in play. Either it's healthy or it isn't. Now it could be that people might be willing to put up with more in a mono relationship. I don't know. But the fundamental dynamics are still the same.
