If a Women think marriage is HOLY and Institution of marriage as you say, she will never leave her husband.
Both promise at the time of wedding both will be together in “pain and pleasure”
but for todays women,she says to her husband, take your pain to you give me pleasure only.
thats the significance of marriage in modern times.
before we think about man abondon his wife, we have to think why he Abandoned her.
if he has not taken any money from her or demanded then there is no question of making money.
he left her, coz she will not leave him but harass him, and if he is togather he will die half age.
may be she is not giving him marital happiness
she is doing her responsibility
she is grumbling and murmuring whole day without reason.
she is not cooking or cleaning which todays most women call it Slavery (assuming she is house wife)
she is working still think that husband has to pay all her bills.
she harass him
she give threats of filling false cases.
she has Affair or had Affair
she told lie at the time of wedding about her
she hide her past
there should be some reason to leave. coz no man will run away from his marriage; unless force him to do.
