...I realized my kids emotions mirrored mine. Not 100% but at least by 70% (if you can measure that with %). that's when I felt really guilty for the devastation they lived through my devastation the first couple of months. That's when I realized I was the strongest role model they had. (Thank God, my brother (their uncle) stepped in and became their male role model)....but I tend to believe kids are affected because of the way their parents deal with it and all the consequences a divorce brings (standard of living, step dads, step moms, change of routines, 2 houses etc etc). It's not a theoretical-vague thing. These are things we can improve, affect and decide how to handle.
