You sound a lot like the catholic church here. It could have been 25 pretty nice years, and in the last 5 both people found that they had grown apart over time

You sound a lot like the catholic church here. It could have been 25 pretty nice years, and in the last 5 both people found that they had grown apart over time and mutually decided they might look for something else (maybe after the kids are out of the house, etc if they have kids). I have no idea if thats the case here. Blanket statements on the morality of human relationships are rather foolish.
