Smartcookie, I wish I had some insight into his or her anger. I try to figure out my WAW too much as it is but in the end, the only way to really know is for them to tell us. It would probably have to be volunteered otherwise it may not be entirely truthful on their part if we ask.
However, speaking as someone who is the LBS and very hurt by it, I would encourage dialogue on your part. Patient, contrite, yet loving dialogue. Once he opens up, he would need to do his part otherwise you'll feel resentment.
In my WAW's case, I need to remain distant because her anger causes me to slip back into mild depression. As I mentioned, I suspect her anger is now different than before although I only have my observations of her patterns of behaviour to go by.
