I have a crush on a girl, but I can't show it because of my job?

Im a female Resident Advisor in a university, and have developed a crush for a girl on my floor. The two of us hang out a lot. I’ve begun to feel that she too likes me (I know for sure she is a lesbian). She hangs out in my room a lot, and we talk so much, also she sits super close to me, and our hands would linger over each others for a few seconds more than usual, but I would always pull away. Same with hugs.

However, I can’t be in a relationship with any of my residents due to my position as an RA. What should I do? It’s so hard not to talk with her, hang out with her, and not have an urge to hug her in a way that isn’t just a friend.

Also, I haven’t exactly come out to her, or anyone before at all. I’ve only recently begun to realize that I am probably bisexual. I am still figuring things out. I’ve never been in a relationship with anyone before either. So this relationship thing is new too.

I’m in a limbo. Help! Suggestions? Tips?
