Why do I think she is not having an affair? I have been married to her for 25 years and we dated for 5 so I have known her for 30 years. I may be wrong, but I think I would know if she were cheating on me. In any event, as I said, if she were, that would set me free so I am not sure I have any reason to try to deny this possibility. My own guess is that she has simply lost interest in sex due to menopause. She is moody and withdrawn much of the time but at that time of the month it is even worse. I remember when her mother went through this stage, and my wife (who was in her late teens at the time) always joked about how nuts her mother had become because of menopause. I know there is more to it than that but it is a factor. She used to exercise every day and she had not done that for the past two and a half years either.

By the way, great point about my daughter (and my older children for that matter). I know that what they are seeing now is damaging to them and seeing their father stand up for himself may be the most important lesson they learn and may just save their own marriages years from now. I never thought of it that way.
