I don't know if certain people were meant to be alone or not. Some people handle being alone well, others don't.

My wife's brother will be 50 next month. He has never been married, but has been engaged three times. He has a lot of friends, both male and female. He is not alone. But he will never get married.

My parents divorced in 1962, in their late 30's. My dad remarried a year later, and is still married to the same woman today. They have had a great life together, although they are plagued by health problems today. My mother never re-married. she did have a man in her life for a few years in the 1970's and 1980's, but she never even considered marrying again. She had a lot of friends and stayed very close to family. She passed away in 2001.

Of course there are also those who are alone by choice, who live hermit-like lives. They have very little contact with people. I could not do that, I have too many people in my life that I am grateful for.
