Office crush situation – not sure if there’s potential or I’m overthinking. What should I do next?

Hey everyone, I need some outside perspective because I think I’m too deep in my own head at this point. I have a crush on a girl at my workplace. I’m pretty introverted and don’t talk much generally, especially in front of others. So most of what’s happened between us has been subtle. Over time, we’ve had a lot of eye contact. Not just quick glances — sometimes it lasts a few seconds. One time it was probably close to 10 seconds while I was walking back to my desk. It wasn’t awkward exactly, just intense. Once I asked her for a charger. She said she didn’t have one, but then she actually went and borrowed one from someone else and gave it to me. That stuck with me because she didn’t have to do that. There was also this weird moment where I came back to my desk and she had opened my work notebook. When she noticed me, she moved away quickly, but then she turned back, held eye contact, and gave a small smile. I still replay that moment a lot. She’s asked me for small things like a pen or sticky notes. When our seating got changed, I helped shift things around and she messaged me privately to thank me. She also mentioned me casually in conversation with someone else. Recently I asked for her Instagram. She replied after a few hours saying she has it. I asked for her ID and she gave it directly. No emojis, just straightforward. I followed her and she accepted within an hour. Since then, I feel like she’s not making as much eye contact, or maybe I’m just overanalyzing. I’m not sure if that means anything. I’m also worried about coming across as desperate. Sometimes I want to send her a reel or text her just to keep things moving, but I don’t want to overdo it. At the same time, I don’t want to do nothing and lose momentum. I’m more comfortable texting than talking in person, but I know that might not be good long term. So my question is: Does this sound like there’s actual potential here, or is this just normal coworker friendliness? And more importantly, what should I do next — text more, talk more in person, ask her out eventually, or just chill? Appreciate any honest advice.
