There have been many relationships throughout history that were unequal, but that is frowned upon in the modern world. People are now raised to feel they are good at something, and it rarely matters what that something is when being compared to a spouse. As long as both people contribute to the lifestyle, it does not matter who makes the most money or takes care of the domestic work. Both are part of the formula for living well, but not every spouse sees it that way.
Comparing a spouse who stays home with one who earns a living is a quick way to ruin a relationship, and some busy professionals tend to do this. They may be tired, angry or just frustrated at work, and they take it out on their significant other. This type of verbal and emotional abuse wears down the confidence of their spouse, and they might eventually choose to leave.
When the honeymoon ends, it is time to move on to a better life. Moving on from this type of relationship means finding a good quality of life that does not depend on money earned, and finding help is an easy online search. A fuck buddy will not care how much money a person has, and they are not interested in measuring someone against their lifestyle. Fuck buddies are interested only in satisfying physical needs without a relationship.
Being with another person for local sex only is a good way to begin recovery from a bad relationship, and many people have found it also works as a permanent lifestyle. They get the physical relief they seek without exposing their feelings to another person who might hurt them emotionally. It works out well for both people, and they can end their arrangement at any time with no hard feelings.
