As reported by the Herald Sun:
"'If I don't marry you, I'll become a priest.' They didn't get married. He became a priest. And yesterday, he became the pope.
According to a bespectacled, white-haired woman identified only as Amalia, Pope Francis wrote those words to her in a letter more than sixty years ago, when they were just 10 or 12 years old."
As reported, her parents broke them apart after they found a letter he sent to her in which he talked about what kind of house he would buy for her after they married. Her parents didn't like that - but they were only 10 and 12!
And so he became a priest, true to his word to her. Given that degree of introspection on his part, at such a young age, maybe he would have purchsed that house he promised to her, if they had married? We will never know.
