Have kids or you'll regret it. You don't know what you're missing. The last time I was asked when, we had been married 28 years and were 14y post vasectomy.
Instead, we went to school as much as we wanted, we were living debt free before age 50 with our city home and a mountain cabin (now 100% restored) for recreation and relaxation. I retired at 58 and life is good. Hubster is working because he loves it and wants to save more $ for some of his high-end ideas on retirement life. I have nieces/nephews who've had experiences they otherwise would not have had.
My HS contemporaries? Some are on 2nd or 3rd marriages with pre-teens. Some are raising their grandchildren. 50% are divorced at least once.
Yup, kids would have improved my life.
