Congratulations on a wonderful marriage, MistrX. I am but a young whippersnapper, married 4 years, 57.5 to go. (At which point my wife or I will die, per our reckoning :))
I personally take the generally mainstream, conservative Protestant position on divorce and remarriage, in which it is permitted in certain limited circumstances. I do not intend to indulge that prerogative, however. I am determined to forgive my wife if need be even for the few indiscretions which would "allow" me to divorce; though I pray she never tests me in that way. I frankly couldn't even conceive of it, she is so wonderful.
Good on you!
