No need to apologize joerebecca. Sounds like you needed to get it off your chest. As they say in psychology, those that cast blame and do the sneaky things like your husband is doing is usually the guilty party. Instead of admitting their own wrongdoing, they blame.
The aforementioned question I posted - If you post something - "Trying to help a friend" nobody will answer you. Honestly, that is what I am trying to do. My friend is in the above situation. You see, I believe is trust is earned and you can learn to trust someone, but there's a lot of room for IT AIN'T HAPPENIN'! Like my friend, he and I had dated years before he got married and we simply stayed friends. To this day, his wife is still freaked out and jealous. For what? If he and I were meant to be together, he never would have married her! Put it all into perspective! But...every time he threatens to leave - well they have 4 kids..there's your answer. It's just this type of person that lives on envy, jealousy, manipulation and deception - I don't think happiness or trust would grow on me.
My friend's situation sounds like the way your husband is with you. Manipulative. No matter what you say, it will be misinterpreted by him and/or twisted to make you look like the evil one. Hacking your email accounts - first off what I recommend is you clear your cache file on your computer so he doesn't know what sites you went to. No trace. I had an abusive husband and that is what the domestic violence people recommended first and foremost. That info is used to beat you, hate you, accuse you and trash you whether or not it was anything important. Next...set up an email that he doesn't know about. I had set one up in ihateclowns.com...LOL!....Everyone was sending email there so when my main e-mail was hacked he found nothing. But...I have to admit that he and I were both guilty. I broke into his files and e-mail right before we were divorced wherein I presented evidence of 20 memberships/profiles to singles sites while we were married and I took letters/emails that he had been writing to his girlfriends. Needless to say, he was mighty quiet in Divorce Court. I didn't want anything but out...but he knew I could screw him royally on grounds of adultery so he kept quiet and we parted amicably. Normally, I didn't care what he did. I didn't spy on him or anything..just during divorce. It was in my best interest.
Last thought for you, I would leave him. Once a cheater, always a cheater it seems. Only on rare occasions will they change. I keep going back to the thought that without trust, you don't have a relationship, you coexist only. Anyone deserves better than that. People need to be with someone they trust.
