AIO for getting creepy vibes from this guy?

Disclaimer: This is really long. Also, I came to my own conclusion that I'm not overreacting - I started making this post this morning, but after certain events that have occured today, I don't need any more confirmation. However, I'll still post it.

So, there's this guy I (19f) sit next to in my English class in university. We haven't spoken at all aside from when I pass over a paper the professor is handing out, and even then. He only knows my name (and I know his) from the prof taking attendance (it's a small class).

Background (context from before the screenshots): The weirdness starts pretty early on; in case you can't recognize it, he reached out to me on Facebook messenger. I only have Facebook for friends and relatives and don't use it often, if at all. My account is also private, so as far as I know, it won't be recommended to people I don't know. I presume that means he searched it up ... I imagine my profile is relatively easy to find because I have an uncommon first name and my profile picture is a picture of me, which I never thought would be a problem.

He reached out to me to ask a question about some work we'd done in class/asked for my notes, which I gave to him, and we got to talking. It was at like 11pm and I was exhausted, so my judgement wasn't at it's finest ... I probably wouldn't have responded had I been thinking probably. We chatted back and forth for a while, and he asked me a lot of questions; where I was from, what I'm studying, why I'm taking the class, etc. He also said that he liked my tattoo (I have a tattoo of a butterfly on my wrist) and asked if it had any meaning. It does (search up butterfly tattoo meaning if you don't know), and I told him only vague details, and in response, he said that I was extremely strong, he was proud of me, he was happy that I came through on the "other side", and that I was stronger than a lot of girls he knows - really laying on the compliments.

Another weird thing is that he asked if I was in a relationship, and I said yes (true). He then asked for a photo of my boyfriend, and when I asked why he wanted one, he said he was "just curious". I told him no - wouldn't have given one to him regardless.

Now we're at the timeline of the messages. The first 3 screenshots are from Friday, the last 2 are from today/this morning's class. I've befriended the girl I sit next to (I'm between her and the weird guy) about it on Friday after class, so she's aware of the situation. She texted me today during class to tell me she saw that he'd been looking at me a lot, and was occasionally leaning back in his chair to see what I was doing on my phone or laptop. I was aware of it, and I didn't make eye contact at all, completely avoided looking in his direction. After class, my friend reminded me to block him, which I did, and as we were leaving the buildinf, I told her that I was going to go to the library to get some work done before our next class (we have another class together later today), before we split up. I went to the library, and 5 minutes after I sit down and set up, guess who shows up and sits in the desk right next to mine? In response, I completely ignored him. If he messaged me, I obviously didn't get an answer.

It's been about 30 minutes since then, and he's left, thank god. As I mentioned before, I've been making this post since this morning, hence why it's kinda disorganized and scattered and probably really long. But I don't feel like I'm overreacting anymore.

If people ask me why I didn't block him on Friday, the simple answer is that I forgot. Like I said, I don't use Facebook very much, if at all, and I was in class when he messaged me, so it slipped my mind. As for why my friend had to remind me to do it today, I have ADHD (and one of my biggest symptoms is forgetfulness). That's a big reason I made this post in the first place; I didn't know if I was seeing things that weren't there or if I was missing something, but it's been made clear to me now.

I've told my aunt and uncle (who I'm staying with - I'm attending school in another province) about it, as well as my mom (who lives back home), so everyone who needs to be aware is, and I know I'll have their support if anything escalates. Yes, I'm an adult who can make her own decisions, but it feels good to have them backing me up.

Thanks for reading this far, if you have. We have an exam on Friday, which I won't be in the classroom for (ADHD accomodations for the win), and I'm choosing not to think about next Tuesday for my own sanity. However, if the weird behavior continues, I'll take more action. Considering he hasn't actually done anything (other than the texts, which are superficial in of themselves) and most of this is speculation based on observation, I don't know if anyone higher-up that I report to will take me seriously.
