I have caught my husband in lies and looking for suggestions on how to snoop on someone who is technically advanced and who has a lot of work devices. Despite our marital problems, I had always 100% trusted him, but after accidentally discovering that he was privately communicating with an old girlfriend awhile back, I started snooping on him. I was very hurt and confronted him. He stopped and gave me access to his phone, FB, etc so I let it go. He texts women from work and other "friends" after work hours and on weekends and does not see this as an issue. I have asked him to stop, but he only calls me insecure and says it's nothing.

Recently I had to use his work computer for something and checked out the History, only to find that he has been secretly looking at naked women/porn for months. Of course, once I confronted him, he got angry and changed all passwords. After a few arguments and me accusing him of trying to hide something, he gave me the new passwords, but the history is either cleared or I know he is deleting things that he doesn't want me to see. The lies, the emotional friendship with women, the talking to old girlfriends and the porn are all things that are extremely hurtful to me.

I know I had to confront him, but unfortunately by doing that, he now just knows to be more careful. He even told me in an argument than he wouldn't be stupid enough to not delete things. He claims now that I have all the passwords to everything. However, he has a work cell phone and a work computer and it's very easy for him to setup other emails that I don't know anything about. He has countless numbers of accounts, social media and other messaging sites that he uses at work. I can't check the phone records on the work phone and I can't put software on his work computer. He knows better now than to use our personal computers or his personal cell phone. How do I "snoop" or keep tabs on him on his work things? He knows I cannot get access to them. So is there anything I can do? Thanks for any advice.
