At 21 I was a mess and couldn't have done kids (and wouldn't have). I'd already chosen an abusive relationship. After that I went into a dominated relationship with someone twice my age. It was better than the previous one, but not good.
At 26 I had a child, and I found it really difficult. But I was aware of my failings and that I wanted to be a good mother who did everything right, so I went to all the baby check clinics and I always asked for advice, and worked with it to make myself a better parent. I left the relationship I was in when my children were 2 and 4, because I couldn't stand the way their father spoke to them, or me. So I would say it was my experience of abuse that made me a determined to learn, good mother.
But after splitting with my ex, I made the mistake of inviting a frighteningly obsessive, dangerous man into my life, who tried to kill me. Thankfully, the children weren't subjected to that, but it upsets me that they could have been. I then kept in touch with the group of people that protected him, denying the severity until I broke down. My young son did hear me scream during that breakdown, and I'm very sad that he had to see his mum like that. So in this instance there are choices that I've made because my mind isn't right due to abuse, that are not good choices for my children.
But, at that breakdown, my determination to be a good mother drove me to isolate myself from al those people who could hurt me or trigger my symptoms. It also drove me to get professional help for myself and to put in the work to stay stable and stop letting abuse influence my life. So, in this instance, I was back on track being a good mother.
My children are really healthy, they do really well at school and I rarely have to tell them off anymore (they are teenagers). the one thing that I feel they have picked up off me, is that they are shy socially - probably because they've never seen me socialise with other adults, but they have their small close knit groups of friends, and are happy and comfortable in that. They are confident and comfortable in who they are, they are comfortable coming to me with problems and are very sensible and don't have any emotional problems.
So yes, previous abuse has effected my adult life and some of the choices I've made (especially with men), But it has also made me probably a more conscientious mother, than many of the mothers I know who just assume they are doing it right.
