Hey, you remind me of Me. Just have fun with her, get to know her more. Stop over thinking the situation. Let me tell you this, in five years you will either look back and smile at the small (and maybe big) experiences you shared with this person OR look back and be filled with regrets.
I was in a situation similar to yours. It had this girl/lady in the HR department of the company I worked for, she was a very nice person. I was freshly out of college and had no interest in getting into a serious relationship (I guess that gave me an upper hand). But here comes Kylie (let's call her Kylie) flirting every moment she got. With my young mind, at first I paid no mind to it, I thought she was just Friendly and what not. I was very nice back to her. She now and again made some jokes that you would say are inappropriate for the workplace, but I played along very well.
One day, after about a year the games, I just asked her to go chill after work, nothing serious. Without all the details, after that day, we became closer, things happened, smashing (smashing pumpkins of course) took place, etc.
Mind you, she had her people and a kid. But that was not my concern or problem to deal with. If there're connection and it's meant to be, then it will be. Don't force anything, just have fun. Life is too shrt.
Regards,
Me.
