I agree that not only should you tell the person you're estranging that you are estranging them, which our son did, you should also tell the why, which our ES didn't do.
As you've posted, unless you've experienced either being estranged or being the one who estranges, it's impossible "to get it".
The relationship you used to have with your ES mirrors my own as does the way you've described how much he's changed and the part his wife has played.
Ghosting is cruel, heartless and cowardly. You ask what we think you should do, well if I were in your shoes I would write to him, tell him that you can only assume that his silence is because he no longer wants you in his life, and he is in fact estranging you.
I would add that this is the last time you will attempt to correspond with him and will move on with your life as he appears to have done with his own.
I did a similar thing 4 years ago before we moved and sent our ES a 'goodbye' email. I was surprised at how empowering that was, that despite the estrangement not being of our making, I had taken back some control.
I hope that if you decide to do something similar, that despite the heart break, you too will feel that you have taken back some control and be able to move forward with those that you love who love you in return
