My husband and I have been married for 39 years this month. 

The one specific thing he did that convinced me he was "The One" was this: before I ever met his family, he told his very Italian mother, "I'm bringing a girl home, and you better like her." I never had any trouble with her and she respected the boundaries my husband set before day one.  I have used this as a standard of how a man protects the woman he loves.
