So he should have remained celibate for the 14(?) years that his wifes cerebral cortex has been destroyed?
Would you have felt better if he had stopped by every couple days and just ....(I'll just stop there)
No, he should have divorced her and gone on with his life - I would have no problem with that.
But to stayed married simply to control her while not abiding by his marital vows makes a mockery of the marriage. He wants all the rights that come with being a spouse, but he doesn't feel enough respect and love for her to abide by the marital vows. And I am not just talking about adultery, as he has not allowed Terri to have the rehabilitation that might could help her.
I wish he would divorce her and go on with his life and let Terri remain in the care of those who really have loved and cared for her from the beginning.
