My mother married when she was 20, got me when she was 21. She had a terrible childhood with alcoholic and abusive father and a mother who gave all her love to her son and none to her daughter.
Her own marriage was not any better. My father was not an alcoholic, but he was a gambler and there was never a day of peace in our home. They screamed at each other all the time. She also lavished her son with love and affection, and her daughter (that's me) with awful physical punishments.
I was probably six when I started dreaming about leaving my home and I did that as soon as I found my first job when I was 18.
From the moment I left home the only topic of conversation I had with my mother was when are you going to find somebody and have kids.
I was a serial dater (is that even a word?) in my 20-es. I never went out with a guy more then 3-4 times. First little red flag and I was out. My mother hated that. Screamed at me that nobody will marry me and who do I think I am.
By that time I was at peace with myself that I will never have a children and a family. I was never that pretty girl every guy wanted to impress so it was pretty easy to find out who really liked me and who didn't.
My brother married very young to a first girl that told him she loved him and that marriage turned out to be very unhappy with two very unhappy children.
After I turned 30, my mother screamed even more. She couldn't understand that I have zero intention to settle. I was so traumatized by our family that I had zero wish to repeat that.
Finally I did marry. And he is pretty great husband and father. My mother doesn't like him and can't stop repeating that he is actually a horrible human being and I just do not know that (although she got kinder in the last year or two).
For her, me marrying anybody, even if he was abusive prick, was the most important thing in the world. I was happy to stay alone all my life.
I think children are the most important. It is our duty to give them happy childhood. They're not right and before you have them you should ask yourself will you be able to that.
