My second son's first marriage failed. Neither he nor his first wife sought an annulment, because, as my son told me, there was nothing wrong when they entered into the marriage. If he were to say that there was, he would be lying. He thinks that lying to God is far worse than remarry ingredients. I agree with him. 

Apparently you would have him lie.

His second wife is a lovely woman, and they have two beautiful children. (Of course, I recognize that I am prejudiced when I say that.) Neither my son, nor either of his wives are currently members of the Catholic Church.
