Why won't she tell me if she likes me or not?

This girl I work with has been talking to me every day outside of work for the past 6 weeks. We go out to eat 1-2 times a week and I go to her place to hang out 1-3 times a week. She's told me she doesn't date coworkers and since she's starting a new job as a traveling nurse in a couple of months where she'll be gone for 3 months, she doesn't want to start anything serious. She knows I like her because I told her and she also told me she's known for a while. She often drops a "I love you" bomb in conversation where it'd make sense if you actually meant it. There's so many other green flags such as her saying that I'm the only good thing that has come out of this job, that she wants to facetime me while she's away, and that she wants to pay to fly me out to see her. She has also told her family and friends about me and they apparently already take a liking to me. She wants me to meet her friends and family and she wants to meet mine. Now here's the kicker, she never calls me or introduces me as her friend. Yet, when I asked her out on a formal date, she said "You know better. I'm more than happy to hang out or go out to eat." So I'm just confused and after something like that is said, we about like nothing happened. She's told me how much she loves talking to me, hanging out with me, and being in the same room as me. I'm just left scratching my head because even all of my friends thinks she likes me.
