Every word of this can be translated to- I'm drunk, narcissistic and mad about the four grand I just had to cough up. Plus he failed to bully you about claiming your DD on taxes. He's trying to punish you for standing up to him. I hope he does send crazy emails to everyone he mentioned. It will save you the trouble. I know how hard it is to deal with when you're in the middle of it, but all of his ranting just makes an objective observer question his mental health. It is truly bizarre.
