I get so fed up of people blaming step mums on here when all we really want is to help.
Only those who want to be helped/need help will welcome it, that's the problem -that I refer as controlling.
My SM wanted to help too. I now understand, as an adult that she really did mean well. Somehow, she was convinced that my dad and mum were raising me badly, that I had behaviour issues and that I needed all the parenting I could get now so I would grow well.
This attitude caused so many issues. Thankfully, my mum stayed out of it, but it put so much pressure on my dad. She was desperately trying to build a picture of who I was as a child that totally clashed with the image he had of me. Even though I was a child when she came into my life (8yo), it didn't take long for myself to feel that she'd got me totally wrong.
As I grew up, she was proven wrong. I did grow up to be an adult with good manners, respectful, ambitious and just doing very well, the adult child most parents would be proud of. We made up when I had my own children and she admitted that she thought I was doing a great job raising them that she opened up and admitted that she's been much too involved in my parenting and overall too negative.
As said, I've turned out much a much happier and contented adult than her own daughter and she now feels closer to me than her DD.
I myself am coming to terms with the fact that my kids have not turn out exactly as I thought they would do with the education I've given them. I think I've done a good job and they are turning out to be good kids, but I would have expected them to be more outdoor, nature loving, world curious kids. As it is, their interests are very different to mine, and my DS is a very stereotypical kid who likes football, the premiership, his xbox and phone and although working great at school, is not half as motivated getting involved in activities, clubs etc... as I would have expected him to be.
As a child, there is nothing worse than a SM who wants to help by trying to change who you are as a child when both your parents actually think you are a pretty good kid as you are. This is where the resentment grow.
