I've seen the verses. Not applicable when the other spouse breaks the vow. There is no vow left to honor. "Till death do us part" is already impossible because you are already parted. God does not ask the undoable.
I recognize that it is an irreconcilable difference of interpretation between Roman Catholics (which I was) and many Protestants. It doesn't lessen my respect and admiration for my Catholic friends who so believe, though I don't share the belief. If anything, I take issue with the fallacy (IMO) of the workaround of annullment. Annullments are given to those married for years, even with children, as though the marriage never happened. And I'm not just talking Kennedys here. I find that a bigger affront to the Creator than remarrying after being dumped by a spouse. But again, a difference of opinion.
Even Roman Catholic priests who swear vows of celibacy can't keep them. So now even us common folk who divorce due to adultry are to remain single? Where is the common sense?
Funny you should mention anullments. I married my ex 27 yrs ago. We divorced in 2001. Because of the kids, I kept my married name, and didn't file for anullment. Guess what? Pyscho dude hauled me back in court. I'm not going into it in public, but I'm changing my name back to my maiden name, and my cousins are looking into obtaining an anullment for me. If I had been able to escape soon enough, I would have qualified for a civil anullment as well.
The pain of a spouse's unfaithfulness is indescribable. I still remember overhearing a conversation between my ex, his brother, and a friend, detailing liasons with the company tramps. I was 7 months pregnant at the time. It was like a hot knife went through my heart. When the kids are old enough to realize what's going on, they resent and feel disgust for the cheating parent. All in all, a horrible situation.
