You did AWESOME!!! I love that she is curious. I've been saying you need to be more mysterious and this is EXACTLY what you need to do!!! I remember doing the same thing with my H. I didn't give him details, (Heck!!! half the time I was just going to the books store dressed like I had a hot date!!! LOL!!!). But just his wondering and imagination....
I think it causes them to think more about you, and really brings out any potential feelings of loss. While they think they have you as a "safety net" if things don't work out with OP, you are almost like some parent figure in the background (picking them up if all fails), but once that safety idea is in question, and they realize "Hey, some other person might be seeing something in my S, and my S could fall for it.... well, sometimes this upsets the balance a bit. Keep it up...
There is no arriving, ever. It is all a continual becoming.
