What do YOU suggest that JFred can do in order to demonstrate that his wife can trust him? All I see you doing is shooting down everything he says or even does. Has he screwed up? Yep -- he's admitted that. SHOULD his wife trust him again? Probably not, but he's trying to save his marriage and we HOPE she can find it in her heart to try.
Full transparency -- especially for us guys -- is NOT easy to agree to do. It's almost humiliating and emasculating (but yet it's fully necessary). I think our advice to ol' JFred here needs to be "keep doing what you're doing, but know that it's going to take a long while before she believes your changes are genuine."
