Ran into the dude who SAd me and it scared us both?

So I went in one “date” with this guy from my graduating class. We reconnected after graduation and we were flirting around. On our first meet up tho he immediately thought we were gonna hook up, and he tried to coerced me into having sex. I stood my ground and I left after he got touchy with me without asking. So after about a year after the incident I finally ran into him again. At first I didn’t even notice it was him until he saw me, he looked like a dear in headlights and turned the corner away from me really fast covering his face. First my brain went “why is this guy so skidish…OH FUCK” and my fight or flight kicked in. I was heading to the bathroom anyhow so luckily I could regain my composure there but the moment I heard his voice talking to his friends I almost vomited at my dad’s birthday dinner.

I just feel really shook up about the whole thing and I want my therapist so much rn. I feel like shit that this guy seems to be doing well going out with friends… meanwhile I’ve had mystery panic attacks around my male friends and last boyfriend, and horrible mood swings. He was with a girl who was obviously his date, so now I feel like I should have gone up there, thrown up on his shoes, and told her to steer clear of him. I know rationally I handled it well by keeping calm and keeping my ground from afar telling my brain… he cant even look at you, he’s ashamed of what he did/ scared of his consequences, you’re safe from him… but it was just so weird.
