Hmmm...what you can do is install Pandora PC on the computer, as long as its your computer...and find out what he's up to. With Pandora PC, you'll be able to see screen shots of what he's looking at, and what time it was happening, you'll see what websites he went to. So if he 'accidently' looks at that stuff again, you'll know it was no mistake. Anyway, here's the link to Pandora PC:

I had to buy and install this on both home computers because my husband had a problem last year with pornography. He was becoming addicted to it during my pregnancy, and I had no idea. When I had suspicions, I installed this, and saw EVERYTHING. Of course it was heartbreaking, but it was something that needed to be done. If your husband has a problem , you need to find out and address it. He could be unhappy in the relationship, he could be sexually unsatisfied...whatever it is, you need to find out. And the only way to know is by installing Pandora PC and doing your own detective work.
If you install it and see stuff you don't like, don't say anything for a week. Let me continue to do what he does. You can print out evidence later...It's a really easy program to use, and I have to say, it saved my marriage. If my husband had continued to look at porn, he would have become deeply addicted, and our marriage would have been in complete ruins. It was the hardest year of my life, but we got past it. I still have the Pandora PC installed on our computer, and I do check them once in a while to make sure that everything is in order....
Good luck...let me know if you need any help. This is a hard time for you...
