What should I do in this situation?

[Anonymous]

So one of the guys I work with sent me a friend request on Facebook and I ended up confirming it. Then the next day he was messaging me on messenger. I’m not gonna get too deep into what we were talking about but he was saying how he thinks I’m cute and was asking me what my type was and stuff like that. Fast forward to now he stopped messaging me and I don't know if it’s because I was sending him one word answers or whatever the case was. But anyway I’ve been seeing him talking to one of my female coworkers offly a lot and i just felt like it was hella shady (by the way I’m not jealous). And I don’t want to reach out to him first because I don’t want to seem desperate. But am I crazy for feeling this way? What should I do?

Feeling what way? You aren't into him, and claim you aren't jealous. So he decides to move on and that's being 'Hella shady'? So he's supposed to keep chasing you around?
And stop with the desperate stuff. Not even close.
If you are interested, hit him up and apologize for being a stick in the mud.

Since you are jealous you either like him, don’t like to lose, and/or are extremely competitive
