I can't remember which wife said that Kody just begins to ignore a wife more and more until the wife wants to leave, thereby making it seem that SHE is the one responsible for the breakup. I totally agree. He did it with Meri, and the Christine called him on it. He made a big mistake challenging Janelle to choose between him and her sons. It's apparent to me that he, consciously or unconsciously, wants to be only with Robyn.
