One thing that gets people in trouble in relationships is the concept of fair exchange.  In the first place, it is my experience of relationships that people always feel they are giving more in the relationship than the other person.  Ask the other person in such a pair, and we will hear the same thing, the opposite way.  We all are very aware of how much we are working to help things out, and we are all very quick to judge the generosity of the attempts of the other.  It is a human trait apparently as deep as our bones.  It is seldom clear to us that we are biased.  But I believe we can assume we are all biased when  it comes to relationships.  We always think we are doing more!  In the second place, relationships are often unfair for various reasons, and this does not stop them from being  good learning and serving opportunities.  Love cannot be denied.  However, sometimes, for all our awareness and hard work, relationships fail.
