shocking long term togetherness

Enough of the "shocking" splits such as Miranda and Blake, Jen and Ben, (and now Gavin and Gwen) etc. These splits are hardly shocking. they are expected, anticipated and not surprising. Often the only real element of shock and surprise is "what took so long?". These stories should be replaced immediately with the REAL shocking tales of.. long term togetherness.... such as.. Tom and Rita, Paul Newman and Joanne Woodward, David Bowie and Iman, Kurt and Goldie, Kevin and Kyra.. well the list is rather short... how do they make it work? How do they still like each other so much? they take romantic vacations together? what is the big secret?? that is the BIG surprise and shock!
