And the same thing happens to women with husbands.
The dating culture is one build on false pretenses. You are always on your best behavior, looking your best, being accommodating because it’s just a date and not something you are looking at dealing with for the next 30-40 years.
People in love get carried away with their feelings and it clouds their judgment.
Then they wake up some day to reality and have no tools with which to cope.
Love is not a feeling. It is a rational decision.
People often say "love" when they mean "infatuation." Infatuation is the feeling most people today equate with love. Infatuation will fade with time, though hopefully never go completely away.
Love is the decision one makes every day--no matter the presence of infatuation or not.
