I really do understand. I had, keyword being HAD, a wife like that once. Everything I did was usually wrong(to her)no matter how much I did for her. She was always right and could cut and hurt with words like no one I know. (unfortunately most women can if they chose to)We finally brode up and she has been through 2 husbands and countlesss boyfriends since. That was 14 years ago. Sometimes it's good to make a clean break and start fresh and find someone that is your friend FIRST. A friend will never intentionally hurt and will have your feelings at heart. If there are kids, try to keep them, I did. They will only suffer and learn the wrong way to treat and respect others.
