Melania Trump is the only one who knows if she loves her husband, Donald Trump. It would be easy to understand if she did not love him because of all the times he has cheated on her. We know he has cheated on her with an adult film star and a playboy bunny.
There were also all those other women who came forward during his campaign. Another reason she may not love him is that he is a very selfish man. I think she stays with him for the sake of their son, Barron. Barron just turned twelve years old in March of 2018.
