My wife and I recently returned from a trip. On the way home, my wife said she noticed a young girl smiling at me; news to me, not a clue.

Regardless, she was upset and I was not supportive. I became angry at being accused of knowing this person, whom I've never seen before. Rather than staying calm, I became indignant and dismissive. My verbal attack continued through the airport, tainting the entire return journey.

I've been unfaithful in the past, and issues of distrust are prevelant between my wife and I.

Does anyone have advice, know of any books or reference material to help me deal with my anger and gaining my wife's trust.

I'm aware that the easist way to gain trust would be to stop getting angry; however, if it was that simple, no one would be angry.

Any thoughts?
