It depends on what region and culture you are from I think.
In the west marriage is more of a business contract than anything.
It has been institutionalized and lost its meaning.
In your example it sounds like religious dogma is the root cause of the poor attitude towards the relationship.
In both cases the root cause is Money and the institution of religion or government which are really the same thing.
It's about the power and control of the few over the many. Invoke the word of god and you somehow have the right to rule free people...
I've never bought into the bullshit. As far as I'm concerned we are all from the same source no matter what your belief system is based on.
Divide and conquer has always been the way of darkness in the world and the few who manipulate the masses will be held to account for their crimes.
As far as money goes, in the current system money is the root of evil. We need to overthrow the shackles of government and religious slavery and start living our lives in a higher plane of consciousness.
The male/female union is as the balance of nature. Each has a role to play to bring harmony to the union.
If you allow the institution of government or religion to guide your views of marriage then you are destroying the harmony and probably don't even know it.
Time to look in the mirror and take responsibility for your choices.
