I'm just as torn as you. As much as I'd like to see you two together I can't help but think that telling her would stilt her opinion of you and maybe force her to think she ought to be at your side whether she wants it or not.

Or that she may find out by other means and scorn us both for keeping it from her.

So tell her then, I think, and let her decide her fate. Offer no pressure but friendship and where she goes is where she goes.
