I think you have a devius mind...lol...I just believe she is keeping quiet while he does what he wants, I don't think he is the type you can argue with. Lets not forget they have two children together, yet he says he loves Terri, yea, sure he does. Michael loves MIchael.
Yeah, but someone posted about Jodi having some 'connections' of her own. Michael certainly wanted Terri dead even before he met Jodi, but I wouldn't be at all surprised if her role is more active than it might appear.
