I had a child as a result of a cascade of horrible things that happened to me. Having a child isn't always a "choice" - "choice" is a tricky thing because it implies that you understand what you are doing, and why, and you can foresee the consequences. Most folk don't.
My family didn't want me, and I was groomed and abused in childhood, which led to a pregnancy in my early teens, which I was forced to abort in extremely traumatic circumstances.
So I spent the next 10 years with empty arms, suffering with PTSD, aching and crying for that baby. I was young, and I didn't understand that another baby wasn't a solution. Society told me that "good girls" were happy, and "good girls" were mothers, had families who loved them, etc. A girl who had been knocked up through rape and then allowed her baby to be killed was not a candidate for relief from suffering, in my mind.
And so I got my baby in my 20s, with a terrible manchild, of course. I tried to make the family that I thought would take my pain away. Selfish, yes. But I did the best I could based on what I knew at the time.
My DS is literally the best child I have ever met. I wouldn't say my life was better without him. But I will say I regret having him because I love him, and wish I hadn't brought him into this messy, selfish, cruel world. I wish I had understood what I was doing and what the consequences would be.
@formerbabe I agree with you that it's the oblivious ones who are made for parenting. I think far too much, and I don't mean that positively. The happiest parents are the ones who don't worry themselves too much with analyzing it all. See above!
