I'm in a Poly relationship with two guys, my fiance and boyfriend. It is 100%, with out a doubt, my fiance's child, I know because I didn't see my boyfriend the month the baby was conceived. But my boyfriend is not only more excited than my fiance, but is also the only one who been supportive and has actually started buying baby stuff. How do I bring it up to my fiance that he should maybe do a little more?
