First of all we need to find the reason why people marry at the first place.
99% of People in the whole world got married because of the following reasons.
1: Companionship. (Sharing)
2: Security (Financial, Social, Psychological)
3: Freedom (Escape from War, Disease, Hunger)
4: Genes Security (For the genes to be able to survive: Rearing Children)
All the factors mentioned above are Materialistic, they don’t last.
Companionship: If you marry because of something you love to share: Eg Sexual relationship. The big question is what if
One of the partners becomes impotent?
Security: What happen if your partner becomes broke?
Freedom: What happen if you have enough to eat: definitely your need will change!
Genes Security: As soon as one has planted his or her Genes. Then what next?
The last reason why only less than 1% of the whole world's population Marry is Love.
If you Love a woman, you will never kill her because she wants to break up with you.
If you love somebody, let them go, for if they return, they were always yours. And if they don’t, they never were.
"Liebe besitzt nicht, noch läßt sie sich besitzen Denn Liebe genügt der Liebe."
