Glad you finally made it to the Other Side. But you want to know "when does the craziness stop"? Hmmm...
I have officially been divorced now for 5 years (next week). His harassment continued as long as I took his calls and there was money involved. He was never one for "doing the right thing", sees the kids rarely, they never go to his house etc. But he sure knew how to scream at me - ranting and raving every chance he got. Until 2 years ago...
I had a serious health trauma and my children told him "no more". In other words - leave mom alone. THe stress was too much. His calls usually left me shaking. He continued to try to call - I would not even pick up the phone. We still had a few financial dealings - D's tuition and books. He knows exactly when the payments are due but never offers a dime unless "reminded". So I remind him. Simply...
"As you are aware, Ashley's next tuition payment is due on June 1 - please submit your payment to me by then. Thank you". I enclosed a photocopy (YES - every single time) with the total amount of tuition for the year and the schedule of payments I had agreed to". I had to treat him like a client in my business. He submitted a check every single time without delay. WEIRD!
So try treating her in a businesslike manner. When mine whined - I just said "talk to your lawyer about it - not me". I think you should do the same. Your wife, like my husband LOVE to use control tactics. You need to let her know she can't get to you anymore.
