What to do in this messed up situation?

He thought I was cheating on him and wanted to get even by cheating me back by putting me as an option and showing me that he can cheat on me with a new girl for which I felt disgusted and blocked him right away without any closure.

I never cheated on him. He simply thought I was cheating on him and successfully cheated on me for which I decided to end things with him by blocking him without any explanation or closure when he expected me to chase him while he is cheating on me

I don't wanna be with him anymore. He cheated. I didn't. He don't know that I didn't cheat. However, now we are not more in contact after I blocked him. I don't wanna give him any explanation or talk with him after he committing a sin of cheating. I don't wanna involve myself with a sinful guy.

Am I doing it right by blocking him and trying to move on with a handsome and better guy who can stay loyal to me and doesn't cheat on me?
