Successful marriage..

Philosophers, thinkers, and psychologists tried to define "happiness," but they did not agree on a specific concept, although most of them agreed that happiness is the feeling that you feel from achieving your basic needs. If you have fulfilled all your needs, there is no doubt that your feeling of happiness will be complete.
Happiness is often associated with married life, and then they speak specifically and exclusively about "marital happiness," and define it as "a state of stability and joy between spouses resulting from affection and understanding between them." This definition indicates that marital happiness has a major role in the cohesion of this relationship. If happiness is achieved, the marital relationship is strengthened, and if it is absent, the relationship weakens, and may even disappear, warning of the collapse of the relationship itself.
