Pending DV case - Is he starting to stalk me???

I have a pending DV case with my ex. It’s really complicated. When he got charged, I wanted to try to get it dropped, as I didn’t feel the incident itself was abusive. I think it was just an accident. And I know people say that covering for them or being in denial, but it’s actually serious for my case lol. But then he got this idea in his head that he’s going to jail and I’m gonna try to ruin his life and he’s spiraling bc he’s freaking out so he’s lashing out at me because he says I’m the enemy. He threatened to kill himself if he has to go to jail (even charged to the max, it wasn’t severe enough for him to go to jail, he’d probably barely touch probation even), said I “had one day” to fix it for him or he’d never talk to me again, and told me twice that he would do “crazy and messed up stuft” and whatever he could to ruin my life in return without catching another case. Which I don’t fully understand because I told him I would help get it dropped and offered a few ways that the court said would help it be dismissed AND I didn’t report the extra stuff he did. He would go between talking, wanting to see me; to “he hates me”, “it’s too toxic” “I have Stockholm syndrome and need to get over him”. When we got a no contact order, we still talked for a little while and then he randomly stopped. He blocked me off every little thing eventually. I just figured it was over so I just let it go.

The other day at work, someone came through (I work fast food drive thru) and asked to talk to me. They didn’t want food, just me. My manager wouldn’t allow it and said he had to leave. She got a name but idk anyone by that name. No one else really knows where I work either. I don’t wear a name tag and I don’t give out my name or talk to customers much. I don’t have really any friends and they live an hour away. Not even my family knows what location I work at, just which fast food place it is. But my ex knows.

The next day, this guy reached out to me. This guy was someone my ex went to school with and he worked with me but my ex said he did drugs and didn’t care for him so he only kept him on social media, not a real friend, which I believed. The guy was on my shift so we were friends even after quitting and texted every few months maybe? But then the day after the incident with the guy, he texted me and started asking me to hangout that night on a limb. I said no maybe a different night and he was really insistent on specifically that night only. After I said no, I haven’t heard from him. But I figured if he does drugs, maybe at least his part is just a spaz.

Idk what to think. It just seems weird. My coworker said to be careful as it could be a trap to follow through on revenge if he’s trying to get ahold of me. But I would like to think since my ex blocked me that he’ll just be done and move on instead of making problems. It’s been 3 days and nothing else weird.
