Yep. You're not alone. I've had earfuls from people who've asked my advice or called on my expertise then not liked what they've heard, and I've had people listen intently, nod a lot, then not act on any of it (which is particularly frustrating when, say, trying to help your best mate dig his way out of debt).

I say tell her to shove it. You've bent over backwards and she's evidently a user.
