John, There has to be more to the story than what we read here. Maybe you havent been paying enough attention to her. Give her the quality time she need with you and then you can go back to work. But I am just guessing here. Nobody said marrage or relationships were easy. Life gets busy and sometimes we forget whats important. My suggestion is take her on a date, just you and her, turn off the cell to business and spend some time together.
But i dont know your personal situation.
Ive been married longer than most of you have been alive. Some years good, some not so good. Ive been married 33 years, 25 happily, but dont tell my wife. Her estimation may be different.
