<human>: Give me the gist of the text in a nutshell

Throwaway, cuz duh.

(I'm Nigerian, he's Pakistani/Muslim)

Almost three years ago, I had class with this guy. He always flirted with me- he would always interrupt my conversations when I would talk to other people, stare at me a lot, copy what I was doing, make inappropriate jokes to me, always try to get my attention, everything. After some harsh words (on my side) and misunderstandings (on both parts) we didn't talk much anymore. I told him that I liked him twice (or, at least I attempted to) but he told he he didn't care and he didn't want to know.

Fast forward two years later, and we either avoid each other like the plague or pretend the other doesn't exist, or stare at each other whenever we cross paths. There have been quite a few times we have run into each other accidentally in the past two years. I wouldn't be bothered but recently my brother told me that the guy was asking him if he was associated with me, but my brother said no and the guy left.

And recently the guy walked into the same class (after school) that I was in with a mutual friend of ours. He stared at me for a few seconds, awkwardly pursed his mouth and left. It was very awkward. There were more incidents after this but this was the most uncomfortable aura surrounding them.

I didn't understand what's going on. I wanted to confront him but he seemed like he doesn't want to be bothered. Along with junior year hassles I couldn't be bothered and I just ignored everything. Now senior year is approaching and from talking to a mutual friend I discovered that the guy and I might have at least one class together. Fuck. What can I do?
<bot>: An estranged pseudo-friend/crush and I may confront each other once again after two long awkward years of glances and stares; What should I do?
