I'm proud of you for blocking him.
I said that because I have my own experience. There was a person that had been in my life ALL my life. This person brought me nothing but grief and sorrow my whole life. Finally earlier this year I decided to send them an email saying my peace and ending the relationship and right after I blocked them. Having them blocked eliminated the uncertainty of the fact that they were going to call or not. I just knew that they couldn't get a hold of me and that it was such a relief and peace of mind.
I am now focused on surrounding myself with positive people who add to my life and not take away.
The game is over! You are the boss!!!!!
