How many matured men can fall in love without sex?
How many men have really loved a women for decades?
What are the reflections of those love on women during those decades?
There is almost no such kind of love as you defined in reality for most men or women:
sex + platonic + care + giving + devotion + ...
What is the odds of two people that with little flaws, are so perfect with each other, stay perfect for decades and die at the exactly same moment which makes the pair a heaven made match. Chances are very slim.
There is no such thing as perfection all the way. That is a perfect reality by the way .
