Should I send him a friend request or would it be creepy?

I saw this guy in my University 3 years ago. We never actually spoke but our simple interactions of saying “hello” or “good morning” was pleasant. I had a small crush on him cause he seemed like a nice guy. Unfortunately the pandemic hit and I haven’t seen him in 2 years. I only knew his first name lol, but he recently came under my friend suggestions on Facebook.
I am thinking about sending him a request but I’m not sure if it’ll come across as weird? Do guys think that’s weird? I don’t plan on making a move or anything, I don’t even know if he’s single lol. I’m so nervous so any advice will be helpful, thank you!
