Re: Should I divorce my wife and leave for the other woman?
Youtube. Take some advice from someone that knows exactly, precisely what you are saying. I have been there, done that, and got the t-shirt. Incredibly exciting at first, i married mine and now we are separating 9 years on. Result, broken families, unbelievable heartache for everyone involved, massive feelings of guilt, disturbed kids psychologies, financially challenged for years, and in the end you are back where you started.
If it is only the sex that is bad then you can work on it together or with a counsellor. Take her away for a weekend without the kids, be romantic, wine and dine her, give her hugs and kisses without expecting sex back, women want intimacy not particularly sex, some of them never really enjoy it but the closeness gives them pleasure.
If you leave for the other women I guarantee that sometime in the future you will regret your decision big time!
