I wouldn’t blame her for having that opinion. Melania was an open target for all manner of hate, scorn and sanctioned disrespect soley because of who her husband is. Most people are not like Donald Trump, who can brush off the unending storms of rudeness to continue saying what he wants or doing what he wants.
If Trump is reelected, and Melanie choses to stay at Mar A Lago, the White House will continue to function just fine. They can serve the country in their own way.
