In real life, if you cut off any possible method he had of contacting you, and he’s not a total jerk, he is likely going to take that as a teensy weensy hint that you don’t want to talk to him at all. And, if he’s got any basic decency, he’s going to respect your wishes.
You sent a pretty strong signal that you want nothing whatsoever to do with him, and he’s respecting that. Consider that door closed and move on.
