Does this girl like me?

We're both girls btw and I used to have a crush on her but now I just thinks she's cute but recently I've noticed she looks at me a lot usually it's just when I'm cleaning up somewhere and it's a pretty decent distance from her so I thought she was just making sure I'm doing everything right but even if she's not working the day I am she'll sit at te closest place to where I'm working and I'll see her looking at me out of the corner of my eye. Sometimes she's asked to be on the same station I'm working on or she'll try to get me on the same station she is and she says it's cuz we're friends which we are but I'm kinda skeptical about that being the reason. Also I'm friends with a guy that we both think she likes cuz she's really flirty and touchy and stuff with him one time she even grinded on him but if her friends or anyone else mentions him to me she'll look at them like they shouldn't be saying anything about that to me but I didn't read to much into that and also recently Ive notice she's in my personal space a lot like if I ask her for help with something she'll stand really close or she'll have our arms brush together and she doesn't do anything about it but ill back away just in case she didn't mean to I don't know if she's bi or lez but I know she has a boyfriend so she's not lez but I've seen a few rainbow things she has so I guess it's possible she's bi? I don't know but what do you guy think does she like me in that way? Or is it just a friendly thing?
