This viewpoint is completely sustained by the adherents of polyamorous relationship. Their experience refutes the label about the perniciousness of love triangles and polygons. On the other hand, they prove that “two and even more” could be the optimal formula for the strong relationship.
For example, a lady confesses to her spouse that she really loves someone aside from him. And a guy agrees to determine an union that is triple encourages their spouse to cheat or even helps her to consider new lovers. Such a unicorn husband just isn’t jealous. He gets satisfaction through the known proven fact that their beloved girl interacts along with other guys both intimately and emotionally.
