My xh did write almost the exact same email. He accused me of dragging my feet when he was the one that wasn't providing the necessary documentation for us to move forward. All he wanted to discuss was his missing mail...keep in mind, he had 5 mailing addresses and the bottom line...he was looking for junk mail.
They all accuse us of dragging our feet because they don't want to do the work and want a quick fix, which means we are thrown off course and if we didn't stick to our guns, we would get less than what we are entitled too.
Your h is following the script to the letter "T".
How are you holding up in your area? Are you okay?
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
