Have you ever considered dating separately? Unicorns are so rare, and then, when you do think you've found one, she usually turns out to be a pony with a fake horn glued to her forehead.
Poly can be extremely enjoyable dating as individuals. Sometimes after you date separately for a while, one of your OSO's might develop feelings for your partner. Then a triad can develop naturally, not as a pre formed requirement.
Love withers under constraint; its very essence is liberty. It is compatible neither with envy, jealousy or fear. It is there most pure, perfect and unlimited when its votaries live in confidence, equality and unreserve. -- Shelley
