HD, I'm sorry that you're having to deal with the conflict between your W and kids. Bummer.
I am the youngest in a blended family. I suppose my step and half siblings could have been a bad influence on me, because everyone was so much older. I've always thought of them as my siblings, and didn't think they had more influence one way or the other than other siblings. Your situation brings to mind the question, "why didn't their antics have an effect on me?" The only thing I can think of is that for the most part, my mother and step-father were in agreement about the behavior of all of us kids.
Consider that your W may well be right. Does she expect you to cut them out of your life, or help her be the heavy or what? Might want to find out. It would help if you were both on the same side.
Hope you haven't been blown away by all of this bad weather. Take care. --z
