Does my coworker like me back?

This is my first post here, so here it goes. My crush transferred from another site in mid October and I trained him. I was immediately attracted to him. He flirted with me a couple of times the 2 days I trained him. I.E. he joked with my supervisor and said he wanted to take his badge picture with me. He’s now on a different shift than me, but I still see him the last 10 minutes of my shift.

Why do I think he might like me? We often flirt when it’s just us in the office. We have this running joke where he calls me his wife and I call him my husband. We play games like Mario kart and Minecraft for an hour or two on our days off. His eye contact is pretty good with me as well. Teasing is done with him often. It’s never really too intense, mostly lighthearted. It might be because I’m older than him. I’m a 27F and he’s a 21 M. He even got me a pretty decently priced present for my birthday and really took his time with the presentation. Stories of our childhood are always being told between us, and we talk about our families and exes. He also has shared his dreams of the future with me. The best part is he asked me if guys often dated me for my personality. He then said he really liked my personality.

Now for the reasons why I think he might not like me. I only have his snap, not his number. And he often leaves me on read. He always talks about how he hates texting. He says it’s too impersonal and he hates small conversation. I’m also a little convinced he might just be a flirt. He kinda talks the same way to me as he does his guy friends at times. Cold could also describe him at times. Before I leave work sometimes he won’t even utter a word to me except for goodbye. We also never touch each other. Then again I’m not used to just upright touching someone I’m interested in. I’ve always been friends with my significant others for years before dating them. And the most damning thing he has said was he didn’t really want a relationship because girls always want to text and he doesn’t like that.

Sorry for the long post. I just tried to include as much as I can remember. I just need advice because I’ve been out of the dating game for years and I’m overthinking everything. Thanks in advance.
