Many, which is to say that it's not the framework that makes one satisfied, it's how much it represents what one wants. The people who were suffering in this polyamourous relationships usually suffered because they felt bad about being jealous, not living up to what the community expected of them, not being good enough to let their parents be with other people. What I'm trying to say is that it's not a specific path that makes one happy, it's the ability to choose your path and to constantly recalculate it.
