An honest opinion, please be kind?

There is a girl at work that I like, I have been friendly, fun and non clingy but flirty. I told her the other day that I appreciated her and she said thanks. She is a good looking girl, what attracted her to me was she is smart, intelligent, caring, confident, have a good sense of humor and kind. We speak almost every day, today I told her about some work that had to be done by her and the bad news that I had done the work for her. She punched me in the arm with a smile on her face. I dont know how I should take that, maybe I am reading things into it that are not there. I would not know how to escalate beyond flirting if she does like me. Yes, I suck chasing women
