Sorry to see you are still being projected all over. Yuck. You sound like you are handling it well. Hopefully he will eventually (sooner rather than later) realize you should not be the focus of his anger.
They really don't like being "diagnosed", do they? I told my H very early on, pre-DB, that I thought he was maybe bipolar or having a midlife crisis (that was based on what I knew to be going on in his head). He reamed me over the coals for "putting him in a box." Seems like he already did that himself - read the MLC for dummies manual and everything. I haven't said anything like that to him for months now. Maybe he will figure it out eventually.
