Up, I agree with what you say about committment but it's not always the case that it only takes one person for it all to come undone. It's often the fault of both people but only one recognises the problem and the other partner refuses to see a problem and do anything about it. In how many divorces have you sympathised with one partner, often the "innocent' party, only to have the uncomfortable feeling some time later that there might be 2 sides to the story. Some friends are in this situation at the moment and I'm sure that one of them is going to be bitter about it but I can see both sides of the problem. Am I going to do anything about it? Not on you life!
