I read that note and remember the life I had with him. I was always wrong. It's my fault.
I have enlightening moments like this. Today, I heard xH talking on the phone to someone and this someone was asking for a recommendation for car repair. xH brought up AGAIN a story of how he was 'wronged' by a certain company. Oh how many times I have heard how this company (and so many others) have screwed him. xH is a huge grudgeholder, and I am soooo happy that I no longer am the person that attempts to smooth him over.
Like always, your xH will continued to be 'annoyed' by anything you do, whichever way you do it. If you had found a tax atty quickly, he wouldn't have approved of your choice and told you that you didn't research it enough.
Do things in your own time, as long as its following the decree guidelines. Ignore his emails and his bullying.
