Is it normal for my wife to be so mean.

There are two sides to every story. And it's rediculous how excepted getting divorced ESP when you have children is these days. Work on it change or switch something up. Get help. Go to a counselor. Read a self help book like Dr Laura. Have your wife do it with you if she will. It's crazy how everyone is so willing to say leave em and pull people apart rather then encourage them to stay to together and communicate. Ya knw WORK things out. Good luck
