After being together for more than a dozen years, Jean's relationship with Billie was special. They were not husband and wife and they have never lived together, but the closeness between the two was like best friends or brother and sister - similar to a couple who had long been married.
Usually, after a few years, the relationship between a husband and wife was no longer filled with love driven by lust, but rather love for a companion or life partner, and that was what happened to Jean and Billie Yves.
They understood each other and supported each other well. It's just that Jean had no wish to be a father and raise a family with Billie; he also no longer had a strong physical desire for the beautiful girl. He greatly admired Billie, but he no longer wanted her physically ... So, they decided to part ways.
