Noting a generational shift in the way couples choose to build their lives together, the National Center for Health Statistics confirmed this week that a growing number of Americans are delaying marriage until one partner backs the other into a corner and issues an ultimatum. In the past, a marriage proposal was usually the result of a few months of indirect pressure, but increasingly were finding that what convinces a person to tie the knot is a non-negotiable threat to end a years-long relationship, said NCHS director Charles Rothwell, stating that more individuals are waiting until their partner breaks down in tears and says something along the lines of I just cant do this anymore before asking for their hand in marriage. Today, the decision to spend your life with someone is frequently made under duress, triggered by the recognition that you will lose this person forever if you dont say yes to the all-or-nothing choice you have been presented with. Rothwell added that more often than not, the ultimatums are issued by someone who has just found out yet another close friend from college is getting married.
