“If Newt and Marianne had been separated for 6 years by 1993, why was she with him at virtually every press conference when he was Speaker (eff. Jan. 1995)?”
Marianne, after leaving Newt in 1987 and filing for divorce (but not proceeded with it), went back to Newt in 1994, after more than six years of separation, because he had become the Speaker of the House and she liked being in the spotlights. Newt, I don’t know why, accepted her back, but the marriage link was already irremediably broken ... Finally he filed for divorce in 1998, the divorce was finalized in 1999, and in 2000 he married Callista.
The post #122 explains why - Marianne wouldn't give him a quick divorce and exploited his time demands (the Contract With America, welfare reform and balancing the budgets while having to fight 84 bogus ethics charges filed by the Democrats and not contested by the Republicans on the ethics committee, and later, the impeachment of William Jefferson Clinton) by threatening a "scandal."
It was a way for him, at least temporarily, to get on with all the things he needed to do as the Speaker with the new majority in the House. It was not the best course of action for him, personally, but it was the best he could do for the country.
No good deed goes unpunished.
