In olden times, there were many factors that kept marriages together.

The first is that women did not have economic independence.

Second, society did not accept divorce, and Christianity did not allow divorce except in cases of marital infidelity.

Since patriarchal values ​​were stronger in those times, the accepted rule was that a wife should tolerate, submit and forgive whatever her husband said or did.

The society in general wasn't aware of the lofty human ideals ​​like each one's personality fulfilment and fulfilling life goals in those times.

There were no distractions such as smartphones and social media through which one could connect with acquaintances or ex-friends in an instant.

In general the society lacked a conviction that freedom, justice, and equality are basic human rights and that men and women are equally human beings.

Even if one's partner did not understand, there were many others in the joint family system who would understand and provide emotional support to a person.

Since there were no entertainment media like TV, movies, or YouTube in those times, the only entertainment available for a person was the moments intimacy with one's spouse.

Even if the husband was dominating, stubborn or even cruel, or if he considered his wife as his sexual slave, it was not a big crime in the society at that time.

Even if the wife died all of a sudden, the public generally did not raise any questions about the cause of her death.

And many of the couples lived their lives in dissatisfaction.

All that has almost changed. We are all living in a transitional period now.

Compared to the past, in most cultures of the world, marriage is contracted in the basis of mutual love. Yet, when it comes to the most natural relationship on the earth, it often is so strenuous when it comes to humans. What could be the reason?

The opposite of all the reasons cited above are reasons.

But aside from these, I think the main reason is that humans are not becoming practical when it comes to marriage. Even at the stage of a romantic build up of relationships, there is no conversation or discussion regarding the partner's perspectives on life, whether the two have compatibility; what do they want from their life together; whether there are similarities or commonalities of their life-goals, etc. Most people seem to rush into physical expressions of love in the early stages itself and hence do not do the necessary homework they ought to be doing.

Even in cohabitations, partners live with masks, disguises, and pretense for a long time. No one can stay that way forever.

And if there is a spoiled child, s/he may have grown up to be huge narcissist.

In any case, unless the cliché discourses are ended and society does not encounter life -in all stages of it - with more of reason and strategy, more people will be suffering more pain for longer periods and more people in society will have to be living unhappy lives.
