Single folks with no kids, do you regret or stand by your decision?

100% standing by it. Not everyone has what it takes to be a parent, and I have to admit I'm one of them. I just wouldn't make a good parent. Too many kids already suffering from just that, from ending up as the kids of people who should never have been parents and going through hell growing up. I don't need to add to that statistic. I've got more than enough dealing with myself and my own mental health, no need for an innocent kid to have to pay too. Kid deserves better than what I can provide. Even so, I also just don't have any interest in having kids which makes the choice even easier.
