+1, but I would suggest figuring out a way of letting go of any anger. While that is hard advice and doesn't make sense it is something that a person will ultimately need to do, so let go of it early, and it will help.
I learned that ultimately in most cases, both partners are the source of the SSM problem. One may not be as large a source as the other, but both have some ownership of the situation. If one can realize that, then one can attempt to forgive their partner and release anger.
After I learned to release my anger, I took responsibility for my own happiness, worked on getting a life and then provided my wife with the love (on her terms) that she needed to heal. That combined with a sex therapist who pushed my wife very hard and helped us both visualize what a "healthy marriage" would look like was what really changed things.
Good luck sporto
>43 years of marriage--My wife and I are now closer than we have been in decades. I believe that my SSM is over.
