When you consider they had a 20 year relationship and children but he won't communicate with her at all upon ending the relationship it says something because that is not normal in my view. Unless he is just a total prick but it strikes me that there is whole lot to his side of the story that we don't know about which is driving that approach.
I totally agree. I have a feeling he has spent years trying to reason with her and got to the definition of madness, doing the same thing over and over and expecting different results. Just lifting from the information she has given us, she has said that she always gets her own way and that no one wins with her. She abuses alcohol and is histronic and manipulative in her behaviours. She has written about how she has threatened sucicide on a number of occasions. Academically she is bright but she has the emotional intelligence of small, spoilt child.
She has probably spent most of her life being pandered to and getting her own way due to her looks and strong character. Unfortunately (and not being cruel here) her looks have gone due to age and self abuse and the people around her can see through her manipulations. How many times can we watch the same episode of a soap opera before we reach for the remote to change the channel?
Her tactics no longer work but she can't see it, she is still pulling the same tricks out of hat and hoping he will bite. Her main two are rage and pity. In person I can image her rages are really quite terrifying, she is a big woman, with a big voice and a big personality, I can imagine even as a man when she was in full throttle she would make you quake in your boots. Her rages probably worked in the past, she scared him into submission but he is no longer there and doesn't have to witness them. He has put a clear boundary up with the 'no contact.' I will not see you and I will not be a witness to your rages anymore. She's now raging on social media but it's not the same as seeing a person's whites of their eyes when you do it.
The rages don't work so she goes into manipulation, the I don't know how to fix things card, the almost tearful interviews, the 'he was the love of my life card.' Then she switches back to rage.
He won't communicate because he is done. Her tactics no longer work. He is done.
