What a tragic story - a woman who has it all, and just won't recognize it or take any steps to heal herself. I am so sorry, djar.
My initial response to reading your post is "What do YOU want?"
What do you want to do with your life next? How will it feel? What activities will you want? What kind of friendships and relationships?
I'd spend some time really thinking about that, without the context of your life with your wife.
One way to get at that is to ask yourself "What do I want my life to be like in 5 years?" and feel free to daydream, imagine, no constraints, just what would make you joyful.
Then, go back and look at your current life with your wife and see if the trajectory of staying with her gets you where you really want to be.
My thoughts and prayers are with you.
