First, kudos on the article itself and your writing style - fully understandable and made me laugh a few times. Well done!

Second, having been a childfree single for almost 20 years now, I can't help but agree that it sounds like you've already made the decision. For what it's worth, feel free to read (or not) my article: https://lenmorse.medium.com/15-practical-reasons-to-live-childfree-de399c43ab26.

Either way, I hope you can gain a better sense of your future self and, with your supportive husband, live a life free of this worry!
