i have live few a number of long term relationship and the marriage of the two couple here ring true to me . particularly the realization that when a marriage evolve into one deal with day to day responsibility of bring up child and the daily business of our life and the marriage seem to suffer . but and the difference between the two couple be that one decide to stay together and cope with the reality of life and while the other couple look elsewhere to recapture the adventurous feeling of new love with a new partner . the question become represent do you stay for the long haul and have the day to day routine become part of a rich tapestry and or do you leave to find fresh new stimulus each time the honeymoon phase be over .
