hi there! This is all very new to me too! I am in a Triad. I am the gf of both the wife and husband in the relationship. this def has it's challenges. it is difficult in a way to be an addition in a way, but i think we are working out the kinks a bit. I am still feeling a little like the third wheel sometimes though. but he put my mind at ease one night when he told me i was an addition to their little clan and not just second best.
