Mikey may be happy with things the way they are with Jodi, but remember, it was reeported that Jodi is a "devout Catholic," and wants to get married!
Gee, if this is true, and Jodi hears that Mikey is happy the way things are with her and doesn't want to get married, will he then turn on her, or she on him?
The official RCC position (which much of the hierarchy whispers in a well, rather than shout from the rooftops as they ought to -- that is if they don't deny it altogether as in these PINOs and BINOs in FL) is that what Michael is doing to Terri counts as "murder." That would disqualify the marriage from being recognized by the RCC. If a local RCC congregation undertakes to marry them, there would be some serious repercussions (although, I figure, it would take about 10 years) from Rome.
He was playing to the camera. Nothing more. I'm sure that's what he told Jodi too.
How many bastard children can she have by him before she loses her "devout" standing?
