My husband of ten years is extremely passive aggressive. Should I confront him about this?

A friend of mine described some of my (27 yo male) husbands behavior as being "passive aggressive", so I (24 yo female) looked it up and found this article. http://www.lifescript.com/soul/self/motivation/dealing_with_and_understanding_passive_aggressive_people.aspx It blew my mind. It describes my husband so perfectly it's as if it were written for him. I never knew there was a term for his behavior. I had always heard the term passive aggressive but never knew what it meant.

Should I confront about what I have learned this evening? Do passive aggressive people realize they are passive aggressive?
