Just found this thread & I love it!
I am 39 & married to the love of my life - we have an amazing life mostly, both work decent jobs, we have a good social life, comfortable house, car, buy what we want when we want, no responsibility at all. I would not change it for anything. I've known since I was a teenager I didn't want children. Had an abortion at 21 because I knew it I didn't want to be a mum. People have always said to me I would change my mind, but I have genuinely never ever felt like I am missing out at all. We have 2 god daughters, 8 nieces & 6 nephews - that is plenty enough small people in my life thank you very much!
My only sadness is that I feel like my best friend and I are growing apart - she is the mother of my god daughters. I feel like i no longer relate to her life, and she probably can't relate to mine. That makes me really sad.
