The first of all, The marriage means the smallest basic part of the society.
Its like atom. So, if there is a lot of divorce happen, the society collapse.
Then why society exists? Its because of ensuring the survival of the individual.
When there is unhappy situation in the society like war,poverty...etc. There is way less divorces.
Because, we must colaborate each other to survive.
But, now a day, at least we have food and house.....
Worth or not worth is out of question. Its just a phenomenon.
So, if you cant live without your partner in any reasons(mental,spiritual,material...whatever), your marriage will work well. And you should get married. If not, there will be problem for sure.
