The matter is a very critical issue and is very capable of tearing down the relationship into 2. My advice for the woman is this: she should pretend as if she want a divorce automatically. The husband will definitely come back on his kneels begging, then at this very moment, she should tell her husband that she wants him to do som exercise. But if he doesn't come back begging on his knees, then i think you should make the pretence a reality. I know this would solve the problem. Thanks
