HI Fubar,
We share some of the same feelings. And I've written on SI some of the same questions. So I will try to respond and be not so long as usual.
A few things come to mind. Some have told me-in virtual life-that nearly Exh is angry in general and doesn't hide it when he interacts with me. He made these awful decisions for his life and self. Some are working and some are not and so anger is coming across at me as he also doesn't feel the need to "protect me" or "keep the peace" like when he lived here.
Another aspect is that he is a passive aggressive and now that he is not near me physically, he feels free to lash out. He didn't have the guts when he lived here to just tell me what he felt and thought an bottled it up, as is his way, but now that he hides behind electronics and lawyers and other people, he feels like "big man", it's a feeling as if he thinks he got away with something. He also has OW and family to urge him on.
Some people also tell me it may be because you don't put up with his shenanigans anymore and neither do I. The blinders are off now for us and they know that and may not like it because we can't be tricked anymore.
I don't think you're wrong for wanting your WH to admit he hurt you, I did too. I finally heard it over cyber space and also receive "I'm sorry's", but FWIW the words feel hollow and meaningless when he is still changing our lives and could stop it.
When he knew the pain he would cause and left anyway, no amount of "I'm sorry" is going to be a big enough band aid now and it's strange to admit that, because I ached to hear the words, too.
Yes, I've felt like nearly Exh must hate me also, but you know hate would mean he put towards me some kind of emotion and thought and I think he probably doesn't even think of me in the least. He probably hates hearing from me if he does, but hate would be investing emotion in me and I don't think he's capable or caring enough to hate me...that would take effort.
I'm sorry that your WH is showing anger and hope you can figure out how to brush it off quicker. I can't say that nearly Exh's anger doesn't bug me, but I'm getting better at getting past the emotion it brings me and getting over it sooner.
I don't know if I helped at all and sorry I wrote so much, but I read a lot of similarities in your post and some I've written. Sorry if I repeated, my brain is foggy.
