First, thank to the mods for creating this forum.
I think I already posted my theory, but since there is a theory page....!
IMO, I'm thinking MS was a casino employee with aspirations for wealth and success, but no promising plan to get their quickly. TS was a woman who created her own success. She could "afford" to be swooned by a guy who could be her "right hand man" and not her provider. He got to ride on her coattails. She got someone to support her at home and at the office.
MS was successful only by association. Maybe he felt that he deserved some of the hero worship, from her, and from the world. But the TV shows and magazine covers, the patients, they only cared about her. Maybe he was tired of riding her coattails and wanted to wear the coat. Maybe there were other women who bought into the successful image MS portrayed and made him feel special. Maybe he started having affairs.
At the same time, maybe TS was discovering more and more about MS that made her uncomfortable--really, husband, your best friend is an ex-con meth head who is retired in his early forties to a trailer? Hmmm. So, husband, you told me that you wanted to go to law school, but that never happened. I thought you said you were ambitious w hen we met. Instead I pay for a chef and a nanny and....what exactly is your role again?
Maybe TS considered divorcing MS and told him so. (Maybe sometimes loudly.) But maybe she realized that would rock the kids' world and would also be a financial debacle. She would not only have to pay him monthly, but also now pay for childcare. Maybe she couldn't afford to divorce him. So she decided to stay and make the best of it. It wasn't THAT bad, after all.
Maybe MS promises the woman he's having an affair with that he'll leave his marriage. But, frustratingly, he realizes, he can't. Without TS, he would lose EVERYTHING: the practice, her money, her social cred, her professional cred, the house and pool, and maybe half the time he has with the kids. He would be back to square one, a guy who used to work in a casino, likely in an apt or townhouse, with little money, or more probably, big money problems. A loser in his mind.
Or, WOULD he have to lose everything? Not if something happened to TS. Like, if she interrupted a robbery in their home and got murdered. He could get MORE money than ever with insurance payments and donations from those who loved her through public fundraising. He could continue the practice and live happily ever after and build a life with his affair lady from the proceeds of the murder. Plus, he could even bring attention to the practice through TS's death.
But he'd have to do it himself, and then he could get caught--isn't the husband always the first person LE looks at? Hmmph.
But, then, CWW jokes about his dopey friend JR who fancies himself a hitman. And suddenly the crazy idea of getting rid of his wife seems to make sense. A break in gone wrong. The guy would probably do it for $10k. For a fee, CWW would make it happen and MS wouldn't even have to do anything except make sure TS is at home alone. MS could pay CWW through the practice and so there'd be no trail of the hit. And LE would never suspect a random dude from MO for the break in gone wrong.
Brilliant! Foolproof! Unless you have ever watched one episode of Dateline.
