From an earlier thread by SW's verified friend:

"I sort of just touched on that but to try and be more clear on my thoughts, I by no means can answer factually. When I first met them they came off as the center of each others world. I think that as Shanann got more and more successful she had become somewhat more distant. Not because she didn't love him just as much but because she knew how to make it to the top and she was doing an incredible job building her team and business. She wanted everything for those girls and even Chris but she knew to do it she had to be all in. I think that Chris not only couldn't handle the constant pressure and I don't think he could handle not being her only focus. I'd assume as she got more and more invested in growing, he got more and more resentful and internalized it. At the same time she was pushing him to be healthy and exceed as well so he probably starting liking the attention he got as well and it spiraled."
It seems SW was so dedicated to growing her business because she wanted everything for her babies that CW grew very resentful. This is a very typical reason for men to start affairs. The more involved he became in his affairs, the more detached he became from his family.
He was the one being selfish and irresponsible by spending so much time and money on his affairs. Then he committed the most selfish act imaginable by strangling his entire family so he could be free of them without any responsibilities.
Even for those who have doubts that he murdered his girls, by covering everything up, he was perfectly willing to let his own family go through hell worrying about what could have happened to Shanann, Bella and Cece if they remained missing. And I'll bet he would've been fine letting them spend their savings looking for his family and worrying forever after, while he cashed in on the house and moved on happily with his life. MOO
