My position is clear, and reasonable, whatever you think, and I do not intend to be patronised into silence by you, any more than I will be insulted into silence by Really Self-righteous.
Presumably you don't think there is a formula that can be used to decide whether one relationship is on par with another relationship? It seems to be your personal preference based on some arbitrary criteria you (along with many others) have chosen..
There are so many different types of relationships - marriages without any sex, marriages with some sexual acts but not others, emotionally or financially abusive marriages with non-abusive sexual acts; marriages which don't produce children; marriages that result in poverty and hardship; polygamy; marriages of duty; marriages of convenience; loveless marriages; marriages that appear horrible but the people in them are happy etc
I don't see how there can be any objective judgement about the quality of a marriage, though obviously society through Parliament, judges, social workers etc can legislate against certain behaviours they view as having an unacceptable cost to individuals or society.
