Grammy winning singer, songwriter and producer Ne-Yo talked more this week about his polyamorous relationship with three women, explaining the rules and how the foursome makes it work.  We learned how he divides up one on one time with each woman, the importance of group time, and what each woman can never, ever do if they want to stay in the relationship.   Ne-Yo went public with his unconventional foursome last spring, explaining that after his very public, very ugly divorce , he wanted to live a more open, honest life.
