Not sure if this was common knowledge, but Janelle left Kody after birth of her last baby (after huge fight w/ Meri) and lived separately for 2 years
She seems the least "needy" wife and had a good job so could have continued to support herself and her 5 kids but went back after he advised he was moving the family to Utah:
