I am feeling the accumulated sadness of 15 years as a divorce lawyer. She said about half of the couples she deals with could have stayed together. Marriage to the right person is happy. If you're unhappy, you're with the wrong person. We need to learn to deal with it, instead of looking for someone to blame for it.
Love is an uncontrollable emotion.
It appears and disappears automatically. It is a stage many relationships go through, and is followed by a different kind of love. Acting responsibly and working to live up to your commitments is not dependent on emotions - it begets its own emotions. Marriage is personal and private. People in happy marriages shouldn't talk to others about how they deal with their problems.
