The only good thing about raising them alone was that I had the money to do it.
But I have not found kids to be any kind of a satisfactory substitute for the companionship of another adult.... Of course, maybe that's just my kids!
We were married in our very early twenties, and when the priest asked me about having children, I wasn't prepared to answer. However, he was patient with me when I said I was open to the idea, and my wife really wanted kids. Over the years we had three, through birth or adoption, and I know now this is what the Lord wants me to do -- even if the last five years has been by myself -- and I accept it, praying every day that my youngest girl and I will be OK. We've made progress; she was Confirmed in April and starts high school in a little more than a month (scary thought, although not as scary as the first night we brought our oldest home from the hospital).
But it also appears that some people walk away from the opportunity to raise their kids.
Some may do so for sound reasons and give their child up for adoption.
Others may do so for unsound reasons, or out of lack of knowledge.
(I'm not referring to those who can't participate ... for any number of reasons.)
