Thank you for letting us know how it went! I agree, the one important thing right now is that you think you probably like her. That's good. She also sounds down to earth to me, pragmatic, professional: Like when she says "we'll deal with the attachment when it happens".
And you were brave, telling her that there is a secret you cannot disclose right now. Well done! So if there ends up being an elephant in the room, at least she will know there is one! That's much better than an invisible elephant!
