So nice to hear from so many who share my basic views and choices.
Keeping my life and those of my DW and dogs going is challenging enough (and is often grand) without kids. The lives of my friends with kids, all smart, capable and well off, look mostly like hell to me. Many of them have great kids, and gain a lot of meaning in their lives from having them, but I can't go there.
I too bristle at the cultural norms to have kids, and that tends to reinforce my not wanting to have them.
I agree that the biggest problem our planet faces is overpopulation, and I don't want to contribute to that.
DW changed her mind and wanted kids badly for some time, and that caused some pretty dark times in our relationship, causing both of us real anguish (her not getting kids, me preventing her from getting something she really wanted). I think we are well past that now, and but it continues to motivate me to demonstrate that life without kids is a good thing.
