Date men from Canada / Ontario / Markham, 71 year old

Date a man from Canada. I WAS married to a woman that I love very much. She is my best
friend. We have the best time when we were together. Recently we are Separated.
We were almost identical in our taste for food, movies, music, colors and our own humour that we have developed together. Some of our best times were vacationing together.
I am torn between two sides to our relationship.
The best friend that I loved and adored and the lover that is virtually non existent.
Best Friend- I miss my best friend since we are apart.
We had been together for thirty years of laughter and adventure.
Our friendship is the only thing keeping me in the marriage. I can't
begin to tell you how well we click and how much fun we had.
Lover- Unfortunately we are not compatible in the love department and over the past years it had become a heavy burden on me. I am a pleaser and more passionate than most men. She just doesn't have much desire to please or be pleased. Some people are just naturals at art or music, they don't have to try hard and it just happens. I think sex and romance can be like that and unfortunately my wife just isn't a natural and has no desire or drive to try.
I have strong desires and I miss making her hot chocolate when she wakes up in the morning, giving her body massages or just rubbing her shoulders to ease off the stress of her day.
I can't tell how much I miss the softness of her skin, the scent of
her hair, the beautiful lines, curves and shapes that make up the most beautiful woman. I miss her laugh lines(that I am responsible for). I miss the little roll in her tummy and her smaller sagging breasts that age and time has blessed her with.
The part I miss the most and is slowly killing me inside is the look in her eyes when she wants to please me and make me tremble with ecstasy. I haven't seen that look in years.
I have been so unhappy the last seven years. I've been told that there
use to be an energy around me that made me special. I feel that my energy has been dying for a long time.
I fantasize about having an affair with a woman who is in the same
situation as me.
If we could only find each other. Maybe if I'm fortunate, the
passionate side of me will eventually dissolve and my desires will no longer haunt me and I will be content having my X wife as
my best friend.
What do I do? Half of me desires to touch and please a woman and to be
touched and pleased by a woman. The other half of me is trying to justify betraying my best friend.
