hey /adv/,

so i have a female co-worker(well, she switched positions, but we used to work together for years), who lately have been opening up to me(as in, talking more at the workplace, asking what i think about romantic stuff on valentine's day, inviting me out for beers), and i didn't really give much fucks about it, as i am pretty much general autismo.

However, as the weeks passed, i grew to like her pretty much, but i can't decide whether she actually likes me or not. On one occasion she asks me to have breakfast with her, where she promises that she will prepare breakfast for me the next time(as i don't usually have breakfast). Then she goes on ignoring me on a company party. She messages me in the office, and we have something that i feel like a great chat, then suddenly she stops writing, and starts ignoring whatever i write.
She hints that we should go dancing as our styles match so much, but then goes all serious when i jokingly bring that up in a facebook conversation.

I'm fine with her not liking me that way, but these kinds of mixed signals just drive me crazy. Is this normal behaviour for women? Is she just playing with me?
