This is logical thought. Relationships run on emotions. For most of history marriage's sole purpose is to create social security for women. That is really a problem, because once a service is provided, there is always a scope for improvement. If there is a crisis people are busy solving the crisis, in times of relative peace people think they should be optimising for a better deal. There is always a man better than you. Somebody is more healthy, wealthy and spends more on his wife, and you are continuously benchmarked against him.

Heck in most cases you might even be getting benchmarked against a fictional figure who exists only in her imaginations.

The more you do, more that fictional figure gets better than you, and you are expected jump over the bar she just raised. Sooner or later you will burnout and she will hate you for being weak compared to the hero that exists in her mind.
