First, I'm so glad you're determined not to make yourself responsible for the wrong things your family did to you.
I've looked into the descriptions of attachment styles, too, as I'm a dismissive type, according to T. (otherwise known as omnipotent denial). I think you could determine better than anyone, which category most describes you, just by thinking of how you are with people. But, again, it's complex and people can be mixtures of styles.
