Nothing in your article is a helpful suggestion for finding love, because love is not a person, place, or thing to be “found".
Love is a verb.
Love is something you do, not something you possess.
Yellow notebooks are possessions. Marriages are not comparable to inexpensive, disposable manufactured products. Love is not designed, manufactured, and delivered to your door by Amazon.
The thinking in your article is dangerous. You’ve outlined a map to misery, and tried to sell it as love.
The real answer to your question of how a woman can be attractive to a man long after the sexual allure of her youth has faded is this: Be the type of woman who can offer an attractive man something more than sex.
And spare your “friends" the self-righteous indignation of your moral outrage. Do not judge others by whom they choose to love.
