To stay single or have a partner is a personal choice. Invaribily it is based on the circumstances at that point of time that the indivadual faces make him pick this choice. It is true that the percentage of people who pick this chocie is very low. I feel that there is nothing to feel great or feel sorry for this. I was married , but my wife expired 5 years back. When she expired our son was just touching 2 and did not even start talking. After that I decided to stay single, as I felt and still feel that true love happens only once. I am both father and mother to my son. He never felt any deficency. I am also a decentely successfull professional.
