First let me say that I'm so sorry for the turmoil that is inside you. Love has no age, it's in the heart. However, you have children to consider. It's difficult to step back from a situation that consumes you. You have to ask yourself this question -- are you in love with this young woman, or are you swept away by the attention, devotion, respect, sex, etc. that you may be receiving from her? Does this young woman truly love you, or are you a wise, older, father figure for her? In ten years, will she have outgrown you and look for a younger man? Will you be hurt? She doesn't share the same wisdom and life experiences that you have. She has her entire life ahead of her. I'm not trying to negate your feelings, just am trying to tell you to look at it from all views. Another thing, show your wife the respect she deserves. She's the mother of your children and deserves your respect for that alone. Would she consider counseling? Is there anything left to salvage? Is there resentment or other issues that is the reason for the lack of sex? I would suggest that you slow down, do some serious evaluating of your own life, and perhaps seek counseling for yourself. Is your self-esteem shot? Please don't do anything rash, but if you both decide that you are truly in love for the long haul -- even when you're 74 and she's 43 -- I wish you happiness. Good luck with whatever you decide.
