How can they? That is the problem with this stuff and you also have to remember that people are different. I really feel having little to no contact with my wife is strengthening her resolve and numbing the pain of missing her children.....will it last for ever, I don't know but I really don't think it makes a hill of beans what I do. The best thing I can say is that I am getting stronger when I focus on my life and my kids and think less about my wife. It may not save my marriage but I sure feel a lot stronger as an individual.
