There’s no taboo and people “living together” are routinely married everywhere (probably in every church). In the Catholic Church, when they go to prepare for marriage, they are told to live apart until they marry. I assume the same was the case for these people.

I agree. I would add "told to go to confession" to your comments though.

“Go to confession” for a cohabiting couple wanting a Catholic marriage would be the first thing! Then they’d be told to separate until the wedding.
