Thanks for all the above advice.

I think I need to learn how to clear my mind and focus on what I am doing. I also need to be patient and not try to rush things or be too eager.

I think it has become obvious to her that I like her now, she has started to call me by little nick names (I won't say what they are so I can remain anonymous) and is talking to me more then before.

I don't want to be misreading the situation, she may simply enjoy my company. I would be happy to be friends with her as I enjoy being around her, but I'm not sure how I can ask her on a friendly date without it seeming like more than that.

If I can only get to know her more outside the dojo I can decide if I want to simply be friends or more than that.
