Does the present divorce rate in the western society not show that people are becoming difficult to make happy

No doubt a divorce occurs when one partner or both of them fail to make eachother happy. But the alarming rate of divorce and a shameful frequence of infidelity in the married life shows that atleast one of the partner is very difficult to please and satisfy. Does it not show that the faith in individuality is getting out of hand?, that the element of sacrifice necessary for the fluent working of a relationship is missing in the western society? Does it also not show that we have easily accessible and consequently easily attainable men and women all around us which makes for us easier to get dissatisfied easily? Will any honest person tell me that he or she will leave his or her present partner she or he is unhappy with presently if there were no easy prospect of getting a new partner? Aren't we easily unhappy because we know that we can access it easily next door? Does our present system of relationships admit any sacrifice?
