Yes, that is true. He would have hit his "wife"...who that individual woman was, is irrelevant. Because it is him that has the problem here.
It's too early now but at some point J4J may want to try and understand what has happened, and how she ended up in this situation. Respect are just brilliant for this...their number is listed at the top, in the DV webguide, and there is a myriad of books to explain too. I personally have found the books aimed at the abusers to be more helpful in describing their mindset.
Learning about what is wrong with abusive people is very empowering, and we will still be here when J gets to that point.
An hour at a time is the best way, I know that is how I dealt with it. And feeling that you are allowed to cry, sob, shout, whatever, all helps the healing process to begin.
J4J, I wish you a peaceful birthday, and the beginning of finding "you" again, so you can have peace and happiness with which to shine on your children.
You are an extraordinarily brave and courageous woman. I am in awe.
