I asked her if she wanted to come with me she said definitely?

I barely know this girl but we have been chatting and flirting for a couple of weeks now at work. I am les and she knows I am les and I think she knows I like her. People say that I am hardly subtle. She kept bringing up that she wanted to go boxing which was something I had mentioned to her before so I said 'if I ever go we should go together ....only if you want' to which she replied definitely. If you knew a les liked you and you were straight would you still lead them on? She notices lots of small things I do and asks me about them and remembers lots of things I say as if she has been stewing on them.
