When two people in a relationship are not at their best, we tend to believe that there is a serious conflict that is causing that situation. But sometimes this is not the case! Often what happens is the relationship has entered a negative dynamic: the two people have lost many of the positive things that used to be there all the time. This makes people fall apart and creates conflicts in the future.
Fill your relationship with details! Many people believe that love does not need evidence or demonstrations, but this is not true. Details make a big difference.
