I think he should just go forward based on the assumption that his wife cheated on him right before they were married, STILL lies about it (and conspires with others to cover her story), and has the character strengths and flaws that he describes in his posts. And then decide if this is a woman he wants to remain married to.
Seems to me that there are many more CURRENT issues on which he can -- and should -- make his decision. Badgering her to "come clean" about something he's already caught her lying about is not only counterproductive, but it makes him look WEAK to her. "I know all about you and ______, and we both know you're lying right now. Please stop it" is a better approach, IMHO.
