Why Won't Nick Cannon Just Sign the Divorce Papers and Let Mariah Go already?

Nick Cannon filed for divorce from Mariah Carey since 2014 and according to TMZ the couple agrees on the property settlement and joint custody of their kids whose names escape me. One is named Morrocan. I think. The other? Hmmmm….Don’t remember. But seriously. It is two years later and Mariah has a new boyfriend/fianc√© and she is popping to marry this new love and Nick is standing in the way with his jealous passive aggressive I-don’t-want-her-but-you-can’t-have-her buffoonery and it just is completely ridiculous at this point. Why won’t he just let the girl move on with her life? Seriously?
