Is Melania Trump an abused wife?

Abuse comes in many forms, and I'm not suggesting that President Trump beats or rapes his wife, but judging by the way he attacks his opponents, I think it's fair to say that he keeps her in line through a form of mental/emotional abuse. That's why she's always silent in the face of his cyberbullying and behavior that is blatantly the opposite of what she encourages in her "Be Best" campaign. The fact that he had affairs clearly demonstrates that he doesn't really care about her. She's merely arm candy to make him look good.
