My co worker is acting odd, could it be that she likes me romantically?

A girl at work went from being really friendly to nervous and not making conversation and I’ve never noticed anyone else getting the same effort. Like she would say “hi *name*” and “bye *name*” with enthusiasm and would ask me how I am etc. One day she said good morning but seemed nervous to me. every interaction seems a bit flustered or awkward. Like she wouldn’t look me directly in the eyes and they would sort of dart around anywhere but into my eyes. she has been coming in early and will say hi or morning to me as she passes, providing i am alone or near where she walks to go to her locker. Recently she has diverted paths to walk past me and say hi if I’m further from the door, but if I’m already talking to someone she won’t say anything. She’s also passed me in the corridor and said hi and gone to ask how i am but her voice quietened at the end like she lost confidence halfway through. i was chatting to one of her friends at work and she turned around and saw, she sort of stood nearby rubbing her arm like she didn’t know what to do with herself. When she looked up at me I waved at her and as she started walking over shot me finger guns (very awkwardly but i thought it was adorable), and i started jokingly teasing her about something which she went along with. The whole time she was beaming and laughing, and then after a few minutes of us bantering she went back to her work. I playfully threw a bit of paper at her head, and she looked blank until she saw it was me and she burst out laughing, I haven’t seen her be like this with anyone else. when I saw her again she said hi to me and asked how I was as she passed, then 15 minutes later when leaving the room said hi again. She won’t talk to me if im already in conversation though. There has been a few times I’ve quickly turned around and caught her looking at me across the room, but then other times especially up close she acts like I’m invisible.
