Hi - well, from my perspective I'd rather a guy came out and said what he was thinking/feeling rather than leaving cryptic clues/messages (as in my case!) I'm sure she'd rather you were straight with her from the outset.

Perhaps arrange a time when you can get together away from class and hang out for a while as friends, see what happens. BUT if you like her, go for it. I know easier said than done. From reading your posts, it sounds like you're good friends and that is the basis upon which all good relationships are formed.

Keep us posted.
