Take the actress Calista Flockhart, who recently wed Harrison Ford after an eight-year courtship.
I have met many men and women who have missed the golden window of opportunity and are now picking up the pieces.
Tragically, many women waste precious time on a relationship that has led nowhere and, in their late 30s or early 40s, find themselves desperate for a baby and looking for a new partner.
In fact, his progress to the altar has the speed of an elderly snail.
And while three-times-married Ford, 67, may love Flockhart, 45, this delay doesn't bode well for the couple's future.
Others put all the pressure they can muster on their man, have the wedding of their dreams and then find it turn to ashes because they haven't addressed the underlying problems that kept them from the altar in the first place.
