Seems you've hit the classic conflict with Nix and may not (?) understand the female needs vs the male needs. Please see our last post. It would seem unlikely that Nix is truly cabable of blossoming in a poly relationship without doing some serious self analysis of her current belief system. Her "true" needs (primary) feel unsecured & threatened. Whether you can give her the proper assurance that those needs are understood and you desire to meet them will be your choice. You may or not want to and in fairness - it's time to "call a spade a spade".
