Do most women who choose not to marry or have children end up regretting it later?

People make their own lives. You are no doubt aware you could have found a husband and had children. For whatever reason you haven't chosen to do so. Perhaps it's because you never found Mr. Right, perhaps your alternatives were always more attractive. The truth is, however, that even now you can find a man and even a man with built-in family. Depends on how badly you want something whether you will go for it. Don't worry about whether other women have regrets. Look at the number of questions on this site from married men and women who regret getting married and have all sorts of problems with their lives. You have been spared those issues up to now. Your life is as you have made it...and it will continue to be as you make it. Focus on what you would like. For example, where would you really like to be in 5 years? Married to a man who has some family, single, with a boyfriend, whatever. If you can envision a goal of some sort, then fix that goal in your mind, whatever it may be, and focus the next five years achieving that goal. You can do it. Go for it. You life will be what you make it and what you make it will be what you want.
