I have a good number of friends that are not in relationships and never really have been … single lifer's! and a number that have no kids ..didn't want them!
That's quite strange really in that I am now 66 and have never had my own children. That was purely down to circumstance in that I got married for the first time when I was 30 and she didn't want children. Divorced after 10 years, re-married a couple of years later to a lady with two boys who were 10 and 8 years old at the time. Shortly after we got together she was diagnosed with cervical cancer so basically had what was needed taken away.
Six years ago, first grand daughter was born and I can honestly say that I have marvelled watching her grow and develop. It is really only now that I know what I have missed, as I say, through circumstance. One of the few real regrets in my life....
