Some tea leaves here re Guilty indulgence in Dangerous Liasons, NYT has done a long-form out on Melania; these are the bits that struck my eye

 her decision to wear a jacket emblazoned with the phrase “I REALLY DON’T CARE, DO U?” on an official trip to Texas. It was widely seen as inappropriate, insensitive and unbecoming of her office.

Mr. Trump seized on the moment to say his wife was addressing the news media, but a person close to Mrs. Trump said the jacket was actually directed at anyone — both outside and inside the White House — who wanted to criticize her decision to visit the children in light of the administration’s aggressive immigration policies.

The president’s allies say he remains concerned about her reaction whenever headlines about his extramarital behaviors crop up, and he has told friends he feels guilty about the criticism she has faced.

In private, a former White House official said, Mr. and Mrs. Trump give the impression that they like one another, but their rapport is not particularly warm.

One person who has spent a considerable amount of time around her said Mrs. Trump was far more relaxed outside the presence of her husband than when he was around.

(Hence the happy picture with the White House alums at Barbara Bush's funeral and also the smile/frown on the inauguration stand, being his wife is a job for her, pure and simple. And no doubt meeting with the other first couples was a chance to share with others who understood being in the bubble without his domineering presence)

Several people in the president’s orbit have relied on Mrs. Trump to try to get back in Mr. Trump’s good graces when they have found themselves criticized or on the outs.

The sort of Twitter fisticuffs that tend to recharge her husband’s batteries exhaust Mrs. Trump, who has political views different from her husband’s on some issues, one friend of the family said, and has at times been frustrated by his inability to compromise. But, unlike other people close to the president, she is not afraid to share her unvarnished thoughts with him.

She maintains a separate bedroom from her husband, and when the two travel, they stay in separate hotel suites. 

On "Be Best" 

The president suggested that Mrs. Trump choose a different topic to avoid questions about how the wife of a notorious Twitter bully could lead a campaign to spotlight anti-bullying and other child wellness efforts, and he warned her that she was opening herself to such jeers, people familiar with the conversations said. She rejected his advice, and publicly said she was willing to face the criticism.

Despite a tightly controlled rollout and assurance from her aides ahead of the event, one White House official said, Mrs. Trump was still upset by accusations of plagiarism surrounding the launch of the initiative, and was frustrated by the president not backing her up, in public or in private.

There a bunch of stuff on Wolkoff there that might interest you.

Edit to add: overall I am starting to see someone who cynically accepted the job of his wife being very aware of the possibility of him cheating and causing other scandalous situations. And did some kind of agreement like "if just don't shame me too much in public, I promise to stand by and support and do a professional job of being a supportive companion even if I hate it sometimes." But that didn't include being the wife of a president, especially a wild one.
