There is no exception. Perhaps you are thinking of the word "porneia" in Greek, often mistranslated adultery in St. Matthew 5.32 and 19.10. It is certainly not adultery - see St. Matthew 15.19, and St. Mark 7.21-22 where the words for both acts are used in a list (the word for adultery is "moicheia"). The mistranslation is merely wishful thinking on the part of Protestants about what they would like the Bible to say, so as to justify their immorality before man. "Porniea" is actually an incestuous relationship, as is clearly seen by the use of the word in 1 Corinthians 5.1-5, and also in the parallel of Acts 15.28-29 (where the word is again used) with Leviticus 17 and 18.
I really very much doubt that whatever the first marriage in your situation was, that it was an prima facie invalid marriage of incest.
You are probably one of the most priggish, uptight, judgmental and hypocritical posters I've run acrossed in awhile.

You are really upset at Catholic morality, not me.
Your claim to perfection is hollow.
I don't recall a claim of perfection. Its certainly a goal (St. Matthew 5.48), but also not yet a reality.
"claim of perfection"
Said yourself you don't allow "sinners" in your home. That indicates an idea of perfection.
