The doom of the family unit

When will people realize a relationship will never stay new car smell fresh like the first year,that sleeping with the same person does get boring over time ,that yes you won’t always get along,that yes you will not like everything he/she does?
Today it’s all about the :ehhh this is getting too complicated or repitious I’m outta here! Yet most ppl are miserable compared to previous generations?
Society is crumbling and everyone points the finger but nobody looks in the mirror anymore.
