Why don't you just put
@King Martini on ignore since he triggers you after so many posts?
Not responding to dozens of his posts and then freaking out over one in particular negates the whole ignoring thing because it shows your indifference to be a facade loosely covering a boatload of unresolved feelings.
Then you go into this whole rant about where he posted so many times and why can't you reply to one here or there, but "he can post whatever he wants", as if there's some sort of rule you're breaking because it's unfairly being applied to you.
There's no rule, you can reply to him, you can provoke him, or you can ignore him. But when you get triggered it's obvious he's still got some sort of a grip on you, long after it was over and you've apparently moved onto someone new.
Again- why not just put his posts on ignore, is there a reason you are compelled to read them?
