Why divorces - Financial freedom with different spending habbits & goals - One knows that - "I can live without" my spouse. - You can easily get married twice or get partner - Movies prove that point
Now a days both the parties dont understand the spiritual bond of marriage, but think of it as free pass for enjoyment.
Because if it was about fights then our grand parents also use to fight i remember - when fed up my grandpa/grandma use to say I am leaving home & going to stay alone in temple, but still grandma will wait for grandpa for dinner and grandpa will rub iodex on grandma's ankle because he says she works whole day and house is run by her.
Now this is because they had real love...and so our parents.
Those days marriages would work because they had common goal, better life for their kids(next generation) & not their own betterment.
Also in some of the discussions below I saw someone saying to work with women is difficult.
It is 50% true because all indian women - when go on mat. leave then they mis-use work from home right - not ready to work late night at least on-site - not ready to travel for overnight stay(at least in US i have seen) - on weeknds not ready to go to work.
But I will still blame both the parties as they have to look inside & remember that good "parents" makes the strong & happy future generation.
