Many divorces involve a third party who becomes the catalyst in a broken marriage. It is very common for either the husband or wife, locked in what they see has become a boring marriage, to decide to break up after becoming infatuated with someone new. After working for thirty years as one of the UK's top divorce lawyers, I know they almost always fit a stereotype. Sometimes the new relationship works out -- more often it does not. A marriage under strain is never the ideal time to forge new relationships, which may be far more exciting and attractive in the mind than in real life.
