Personally, I thing George lost all control of his life way back in Ohio when Cindy talked him into leaving his job as a police officer. He had done that job and was comfortable with it. Cindy was looking for him to earn more money by being a used-car salesman with his father. Check out Rick Plesea's interview released in the last doc dump.

It didn't work out and they lost their house in Ohio to foreclosure. They followed Cindy's parents to FL. George seems never to have gained a footing. Then, he got them in debt for whatever reason. They separated and he filed for divorce. Apparently, Cindy took him back for financial reasons.
Whatever occurred, George was low man on the totem pole of that family. Cindy is the one who controls all and George goes along with whatever she says. In the beginning, he told LE the truth as a former LE and later caved in to Cindy's demands.
At heart, I think George is a simple man who has suffered from many years of emasculation at the hands of a demanding wife who can find no good in whatever he thinks or does. He never had any control over his own life, he gave it over to his wife and took whatever she handed out. He's been reduced to a simpering non-entity.
Whenever George tries to do the right thing, he is beaten down by his wife. He lacks the ability to confront her and caves in whenever she demands. He had some guts to appear before the grand jury and speak the truth with the emotional bolstering of Mr. NeJame.
Since then, he's continued to cave in to his wife's over-bearing, controlling personality. He knows what's happened. He's afraid of losing his "family" due to whatever his wife has foisted on him over the years.
I believe he'll never be a whole person again. EVER He lacks the emotional strength to continue to do what is right. He is torn between his controling wife and his own conscience.
I don't know what really went on, I've just read all the documents.
Oh, and his latest desire to be of comfort to the parents of missing children and the captain of the SS Caylee Marie? Just another Nigerian Scheme in the making.
