Melania Trump and Donald Trump's relationship has been a big mystery to many. They seem to have the most unusual husband-and-wife romance. However, no matter how unorthodox their relationship is, it seems to work out for them.

Mary Jordan, who wrote the new biography about Melania Trump, The Art of Her Deal, claimed the First Couple had an unconventional relationship. Either they are in love or in a so-called "marriage of convenience," the author confirmed love is indeed complicated, but "Trump love is ultra-complicated."

According to The Guardian, the veteran journalist revealed that the couple sleeps in separate rooms in their different homes. Although they are in the same building, they are not always near each other.

The FLOTUS, reportedly, rarely goes to the West Wing to see her husband. She, too, is never fond of golf, unlike the United States President. She has her own spa and loves to be alone.

As Jordan claimed that they are both loners, they are "perfectly happy" being separated. However, it's not just as simple as being apart. Although they have a "very unusual relationship," they have a strong bond.

The National Correspondent for the Washington Post added that "they have a deal" even from the start. Although it cannot be denied that Donald Trump loves himself, his job and has his own life and spends a lot of time without her, Melania Trump is totally fine with those.

They are living separate lives, but usually together at "some deeper level." They can be compared to the likes of Franklin and Eleanor Roosevelt, as Melania Trump is the second First Lady who is not born in the U.S. She, too, is the "most elusive and sphinx-like," despite new ways of the 21st century mass media.

Jordan continued that although Donald Trump's wife is one of the most recognizable faces all over the world today, there is only a little information available about her. A photographer even said that she's like a ghost, who everyone knows, but nobody does.

Hence, in an interview with CNN, the Pulitzer Prize-winning writer told Alisyn Camerota that it's Melania Trump's brand to be mysterious, People noted. She has been continuously scrutinized for her incomprehensibility, but Jordan claimed she seemed to do it on purpose.

Compared to Donald Trump, whose brand is to "never stop talking," Melania Trump is the total opposite. Although she is the most recognized personality in the world, she remains to be an unknown person.
