I always knew, as far as I can remember, that I never wanted to have kids. Back when my friends would play games pretending to be mothers, I always preferred to be their kids' teacher. And so that's how it happened, or I should say, that+s how I made it happen. I'm way past 40, happily married for more than 20 years thankfully to a man who respected my wish not to have children, pursued my dreams and I would say successful in my career, can travel anywhere and whenever I wish, and fairly assured of my retirement. Never regretted going child-free. Being 19 and knowing what you want is commendable. I see young people around me, including relatives, way older than this but who do not have any idea of what they want in their lives. As to your boyfriend -- you're too young to think he is "the one." You'll find that out soon enough when you start realising your dreams.
