Does she like me or not?

So, I kinda had a little crush on the girl first and joked and tried to flirt some….but she didn’t seem to be interested , then later I come to find she has a boy friend.

I was like fine whatever then Ill move on….

but every time we see each other at work shes like where have you been, and she always laughs at my corny jokes and we talk pretty easy.

then like today she didn’t seem too happy I was like whats up?

she told me about how she had stressful day and then she goes I wanna do salsa joking around, and she comes up and kinda grabs and goes we’d make good dancing partners but she was serious shes like are monday and Wednesdays are ok for you?

I just kinda declined without saying it and then I said why don’t you take your boyfriend….she goes because hes like wall paper.

Now I am just confused I was sure that she didn’t like me and gonna move on and now I am not sure :\
