My wife doesn't have trust or belief in me even though I have never let her down?

My wife doesn't seem to trust or believe in me even though I have never let her down. I have always gone above and behind. This is now starting to take its toll on me. The only time she will have any belief in me is after she has spoken to friends or read it on the internet. She causes delays and arguments nearly every other day.
