Hi mrswilson
all I can say is that no matter what men are always going to look at porn and other women. But think about this, he married you. So there are things about you that i'm sure he loves and appreciate, there are things that you bring him that i'm sure makes him happy, and also your the one thats with him, not those silly pics he looks at on the comp or girls on bikes.
I'm in a committed relationship myself, not married, but we have trust that is one of the biggest factors.
If you two have trust then what is there to worry about? I know it may sound so easy to be saying this, but I have gone through the same thing, sometimes I still do that my self esteam/confidence can hit an all time low. But i'm on antidepressants myself and going through thearpy so i'm slowly getting there.
I too use to hate the fact that I had to leave the house each day to go to work or go socializing becaue I didn't want to be looked at.
Maybe go and just pamper yourself like going and getting a new hair style, manicure whatever.
So just remember he married you.
