Is she really jealous because she has a lesbian crush on me?

This girl glares at me when I talk to other coworkers. We made eye contact once while o was talking to someone late and the next day she was like “is that what y’all were talking about?”
She’s asked another worker questions about her boyfriend and she’s never not once asked me about my boyfriend or anything about how we met. It’s not a closeness thing because her and I are are as close or even closer than anyone else. We will tease and joke with each other a lot. I even feel like when I talk about him she gets so quiet and it’s awkward. Once I was like “my boyfriend buys me stuff” just to test her and she got quiet and awkward and was like “you’re the one who has a discount here”.
I’ve told her before that I used to argue with him a lot and whenever she thinks him and I argue and I’m in a bad mood she’ll try to comfort me. She’s told me she cares about me a lot more recently. She gets upset whenever I call him or talk on the phone with him too and will call me out. She’s a level up from me kinda like a supervisor but we’re still around the same age and I understand she has to do her job but this behavior seems kinda extreme lol.
I don’t understand is she jealous that I have a boyfriend or just dosen’t care enough to ask?
