You really have an amazing insight. So much knowledge of yourself and you use it is such positive ways.
The parallels you mention are pretty astonishing. Reading about your step-mother's jealousy and that of your wife regarding your respective love for your first children as opposed to your second children smacks to me of displaced jealousy. You know, more like "you love the motherthe woman who gave you the first child more than you love me." That's not your void to fill. Self-love and self-respect we must give ourselves.
I knew you were a kindred spirit. I had burgundy hair and bangs that stood stright up in high school and I was pretty out there in college. I am the family eccentric, too. And now I am a lawyer. How did that happen?
