Need help from the LADIES! Please have an open mind!

This seems obvious and I normally wouldn't have a problem here but I work with her so I can't have this go wrong. PLEASE keep an open mind.

So Ive been obsessed (not in a creepy way) with this girl at work since I met her just over a year ago. She is very good looking and has an even better personality. Over the past year I've slowly gotten to know her, though not close, and somehow we've started playing jokes on each other. With that, she recently text me out of the blue referencing our jokes (my number is easily accessible through work, I never gave it to her). Since then, about 6 full days now, we've text back and forth constantly with maybe an hour being the longest there was no exchange. Seems pretty easy, right? Well normally I'd say this is a guarantee but there are a few things confusing me...

1. Whenever I start to flirt with her (over text) she calls me on it right away saying things like "are you flirting with me?" and "you're flirting with me again". She doesn't seem to engage my lead.

2. She brings up sexual things pretty often, telling me specific things about her body and clothes... Her clothes were wet the other day and she seemed to go out of her way to tell me in great detail... She called attention to her boobs (via text) the other day and has told me

3. She's got a lot going on in her life right now, including a recent breakup, and I'm wondering if I am just a distraction.

4. Recently I called her on her making sexual references and she avoided the inquiry.

5. She made reference to her body the other day in what seemed a lead in for me to compliment her. I took the lead and told her she's crazy for thinking she's not hot..the conversation seemed to die off and change from there.

6. I've backed off numerous times to see if she would back off as well and she keeps texting and wondering where I am.

7. She presented a scenario to me about going out with one of our co-workers. I asked, "are you asking for you or for her?"...she said she was asking for the co-worker (I declined). I continued to ask questions leading her to say something like "and if it were for me?". She never asked and changed the subject again.

While I'm hoping I'm wrong, I'm thinking she's just very friendly and flirty, which she seems to be with many people, though I don't think she's texting them constantly. I don't want to be one of those typo al guys who assumes she's into me because she looked my way but there are some things that lead me to believe I'm in, then there are other things that make me believe I'm thinking too much about it.

HELP!
