It was a slow process. He used to be such a wonderful husband. We based our marriage on the Lord and attended church and followed Biblical principals. He no longer has a heart for that and even said to me two days ago that his PRIDE is keeping him from even trying.
So, in answer to your question, I can't pinpoint when he became as defensive as he is today because it was a slow process. Sadly, while still living at home I was so depressed over the kids situation and my H is also a workaholic that I was comatose. It's only since leaving that I've been able to clear my head and see things for what they were.
