So today in a rather awkward "So, when you mentioned that you might be bi, and I've been hoping you would decided you were for my own ulterior motives" kind of way. I managed to convey the information that I was interested to her.
What she responded with was "I don't really know if I am bi" but "thank you". Afterward as we were going our separate ways she did give me a hug.
And in an uncharacteristicly optimistic mood, Wow, I managed to ask a woman out and didn't get rejected. (Though my pessimistic side does have to point out that it wasn't an acceptance either.)
