All couples have unsolvable problems. John Gottman who studied couple behaviour for over 30 years found that 69% of couple problems are not solvable and this is because these perpetual conflicts pertain to fundamental differences between couples which are differences in personality or needs that form a fundamental part of their core definition of self. Psychologist Dan Wile said that in choosing a long-term partner one inevitably chooses a particular set of unresolvable problems.

 

So in short, If you can accept that many of your problems aren't going away in quite the way you think they will, then you can focus on what to do about those issues when they come up.
