My mother, after being sure that she didn't want me, but being talked into having me & subsequently making my life hell for 18yrs, decided, when she met a new partner & started having sex with him that using no contraception was a great idea!! She couldn't use the pill (due to age) and he hated condoms.
She became pregnant. She didn't want it. She asked me what she should do (I was 18, had been told just months earlier that she should never have had me, didn't love me, I ruined her life, she didn't love me etc) I told her it wasn't my choice to make. It was hers. That was the only time she seemed human to me. She cried & thanked me, obviously not seeing the irony of asking your unwanted/unloved child what you should do about a further unwanted pregnancy.
Would you like her to have repeated history? I know that I wouldn't have. Yes, that potential life inside her had the potential to be my brother/sister. BUT they would have lived my live all over again, I would not wish that on anyone.
She would have had to live the last 18yrs again too. I would have spent my adult life counselling my younger sibling, trying to help it navigate the life it had with her, therefore binding me to her even longer. We stopped talking when I left home. But there is no doubt that the person I was then couldn't have walked away from my sibling, knowing the pain it lived with. Opening me up to more pain as I stayed in her life.
The best thing she did, was to terminate her pregnancy. I don't care how it came about, if she had been using contraception, would that have made her a better parent? NO, it wouldn't have, so contraception/not is a moot point.
She made a choice, she made the best choice. For her, for me, for the potential life inside her.
She thinks she did it for herself. She did it for all of us, she just won't ever see it like that.
