on what they deem is required in a marriage.And I would say when it comes to marriage both the husband and wife have duties to be fulfilled.. Period. Likewise everyone has their own reason to marry, and expectations from a spouse. IMO if you made clear your intentions and expectations to the one you were to marry, and he/she agreed then such issues should not arise.
When it comes to marital disputes and issues you will obviously here contrasting stories from the husbands and wives, but at the end of the day if one or both spouses are not fulfilling their duties and are not giving the other what they need and want from the marriage, then the marriage is obviously going to suffer.
Yes in conservative societies often women are told to be patient with her spouse's faults while a man seems to take a whole new approach either threatening to divorce or remarry which is wrong!
In truth divorce is always an option but should not simply be used at whim. Steps must first be taken to try and mend the marriage by both spouses, and anyone acting as peace maker and adviser should do their part in advising both sides to fix their faults with fairness, rather than only concentrating on the faults of one spouse and ignoring the other. Failing which then they should both have the freedom to opt out.
In truth, regardless of how others may define it, we all have our individual and unique rolls to play in all aspects of life including marriage.
