Does he want me too

So I have had a work crush for about two weeks at this point (I’m 28F and crushing on someone who is in his late 20s, maybe early 30s). We work in different departments but we are frequently near each other. One of the first times I worked with him he introduced himself and I did as well, and at first I thought he was cute but wasn’t totally head over heels until I saw that we have similar interests and a similar sense of humor. We’ve made countless SpongeBob references and talked more and more each time we’ve worked together. I even got a pair of SpongeBob flower earrings from a roommate for my birthday and he complimented them and noted that it was yet another SpongeBob reference. A couple of times he would leave work before me and ask me if I was scheduled there the next day (I sadly wasn’t). And when we have longer conversations he gets pretty close to me but not in a way that would make me uncomfortable at all.

He’s just so sweet and funny and sooo so cute. I definitely feel the chemistry there. My doubts come when I wonder if he is this friendly to everyone else that works with him in my department or if it’s just me (especially if I’m the only girl he talks to like this). I also added him on Insta and he added me back but we haven’t talked outside of work yet (it’s a little early but I get worried the longer time goes on). He also will occasionally sit next to me but not all the time when we are on breaks. He’s stolen some glances at me I feel like, but I don’t think he’s necessarily staring at me. But I’m not staring at him either LOL because I’m trying to not be a dead giveaway and also trying to keep things professional. But those are my only concerns, he definitely behaves like a geeky straight guy and has not mentioned any girlfriends or other crushes (nor does it look like he has one from Insta).

So yeah, kinda back and forth on whether he feels the same way I do about him. I also wonder if I’m giving away any sort of clues on if I like him? I don’t feel like I’m a total dead giveaway as I don’t want to make it obvious and then set myself up to be disappointed. I want to be less of a chicken and just message him on insta or try to be more flirty but I’m also worried that he isn’t initiating any of that. But we also haven’t known each other that long so I’m not trying to read too into it but also trying to protect myself in case he doesn’t feel the same way.
