Sounds like he is still acting like King Baby.
Not feeling appreciated for doing volunteer work is pretty adolescent.
I once volunteered at a soup kitchen on Thanksgiving, and had a plate of food thrown at me by a homeless man. It sucked, but, hey, I am bigger person than that, a saner person, and I had a family and a lot to be grateful for. He was in a soup kitchen, for Gods sake.
Also, when he says that you are angry when he shares...this might be something to look at.
My RAH hs had moments of true clarity and recovery. Not as fast as I would want, or as fast as I think I would progress...but he has them. I started to notice, when he pointed out that it seemed like nothing he would do would impress me. ..He might be right. I would be rolling my eyes right away, not really listening, because I had conditioned myself to be defensive of his quacking.
This is a tricky, slippery slope, because they do =quack so darn much!
But, I am finding, just as with my six year old, if I really, calmly acknowledge the good stuff, without overdoing it...with a genuine gratitude and appreciation for it, I get more of that.
