Does she see me as boyfriend material?

We have been working together for quite some time now. I am single and she was married when we got to know each other. Still after a while she started showing signs of interest which I interpreted as just signs of interest, nothing more. Now she is single as well and today I told about an art festival in Aspen in a couple of weeks, something we both like. She responded by asking if we can go to that event together. Just the two of us. At the office when another woman flirts with me she cannot hide the fact she's uncomfortable with that. Is she interested in me or am I seeing too much in this?
