47, married, no kids, and completely by choice. I have zero regrets and I think I'd slit my wrists if weekends revolved around endless soccer games for Billy, music lessons for little Susie, and all that stuff, along with practices through the week.
Regardless of all of that, I'd like to hear from the childless married folks about how their families reacted. My family was 100% fine with my decision, while my wife's family poked and prodded for years until they finally got the picture that we were dead serious. My MIL went as far as calling us selfish, which is the dumbest and most illogical thing I've heard but unfortunately, seems to be the insult of choice towards people like us. After calling us "selfish," her very next comment was literally "Who is going to take care of you when you're old?" I'm so glad she showed us how "selfless" her intentions were.
