Send friends and popcorn

Hi so- ok this is gonna be kinda long. I’m 21 and I’ve got 0 friends to talk to and I want some help.
In my work there’s this guy whom I have a crush on but we don’t speak and only share glances.

We can’t talk cuz I work with my parents so he blinks and I blink back and that’s our hi I guess.
A week ago he gave me free popcorn and the next day gave me and my parents cake from his birthday. But then he stopped “talking” to me.

I was on an errand some days ago and I watched him eating shawarma with his female coworker. I couldn’t bear watching them so I pretended I didn’t see them. I’m sure they saw me. Since then my resolution was to forget about him.

But then today he murmured hello to me when I walked by and glanced at me when he walked by my office. And he broke my resolution like a twig in half and I don’t know what should I do now should I forget him? I want to confess my feelings to him directly and have a clean end but I don’t know how. I’ve been swallowing manga after webcomic and I’ve realised that I want to talk about them to stop thinking of him.

So, anybody want to talk about mangas?
