PTSD OR WHAT?😒

Hi guys. Is it just me or does anyone else have PTSD from being ghosted? I've been feeling some kind of way lately. My ex went ghost on me last year. I tried to reach out, tried to get closure, but nothing. I was deeply hurt and my self esteem was in the gutter for a while, permit me to use that expression. Long story short, it's been over a year and I've really tried to heal, at least I have to an extent. All of a sudden, this guy shows up every now and then, replying my random posts on Twitter, and I end up replying him as well. I'm such a clown. I actually muted him on my timeline for sanity sake, but he's not blocked on any of my social media. Whenever I see him in my mentions, I get this feeling of rage and at the same time, I tell myself to calm down, that I've moved on and all that. Should I just block him? I'm confused. Does anyone ever heal totally from ghosting?
