This is tone policing and white knighting.

"If a husband is loving his wife and laying down his life for her as Christ did for His church she would have no desire to look elsewhere"

The idea that a woman cannot sin by escaping or fleeing the hardship of her marriage is a feminist idea, not a Christian one.

If a wife is loyal she will not leave a man's household, the man who is laying down his a life for her as Christ did, and yet women do that because they are also sinners.

A man's job is leadership, not bathing his woman in emotional tenderness like you imply.
