A survey of local married and divorced people conducted by associate professor Pauline Straun, a sociologist at the National University of Singapore, found that couples who have been in love for a long time are less likely to break up after marriage than those who have been in love for a short time. 
The longer the relationship, the less likely they are to get married.
 some people concluded that if they want to have a more stable marriage in the future, they must prolong their love time.
