Start with the notion that any woman is obligated, somehow, to marry the father of their child.
This is FALSE and even the most devout supporters of the Tribunal process realize that shot gun marriages have always been grounds for annulment after the fact.
After investigating the marriage the Church found that her husband was a brute and was intending to beat her AFTER the wedding since he THOUGHT that divorce was verboten to Catholics.
The Church said: Husband was dead wrong. The marriage vows were broken with the beatings and future of continual beatings. THAT was NO marriage. No "love" and "honor" there, past, present and future.
She got an annulment; the children were NOT bastards and she was free to wed again. She married again to a really nice guy and she is happy again.
Not often I get to see a happy ending. My old school mate deserved the happy ending.
That's an exceptionally foul and malicious thing to say.
