Good people do not abandon their spouses and then take up with someone else in a make believe marriage. If you have a problem with "until death do us part" take it up with Jesus.
Also note Sacajaweau's implied view: that the sacrament of communion is something a person is just naturally entitled to, and daring to inconvenience someone on this point is clearly some kind of grave injustice.
No one should ever be troubled by the merest hint of personal sacrifice, apparently.
