Superiority complex

Firstly, happy new year to all.
It has been a few days now of blocked for good and now that I have no intention and no desire to contact him ever again, thoughts of him have also changed. Where I dwelled so long on the good, and the self blame, because of that, I now see the bad. All of it. Lots of it. So much more bad than good.
And the superiority complex.
One time when he had ignored me for so long into frustrated and abusive contact, his eventual response was " I received all of your messages; some nice some rude "
And that was it..nothing regarding the content or reason for me sending the messages.
He always talked down to me. Like he was the teacher I was the pupil he was the doctor I was the patient. His opinion was fact. He did not even acknowledge mine.
He talked to me like I was one of his employees who was not doing their job right.
I am so glad to finally be seeing the bad instead of the good.
