Really enjoyed the article. I think Friendship is another thing that keeps you going. It frees you from the responsibility that is relationship brings with it. I've been married for 17 years and I would call my relationship more frienship than a husband/wife relationship. We fight, but what I have learnt over the period of 17 years is to resolve the issue before going to bed, don't sleep over a conflict. It has worked for me. We are best of friends and hope to keep it this way.
