Does she even like me??

Hi, ok so there is this girl at work I really like her. When ever I talk to her she looks into my eyes and holds eye contact and smiles. And the other day I said something funny and she started laughing but the other girl next to her didn't laugh.Yesterday I forgot my wallet at home and she let me borrow 20$ and then she went home and made a burger for me and brought it to the store. And ive only known her for abt week and half.And one of manager told me she thought I was cute. I also said "hey" on her Facebook wall and she hasn't responded back yet...so do u guys think she likes me...and what should I do next

Dude....she made you a burger! And laughed at a joke that possibly wasnt all that funny. I think she likes ya

And she has a bf but she doesn't like him...I wonder if I should ignore her
