I think it would be a really good idea if you referred her to AppleCare and let them handle her iPad issue. They're really very good and will be able to resolve her problem.

I also think an active discussion about boundaries would be a good idea. From your descriptions (admittedly from just the few months that I've been reading here), her boundaries look very inconsistent. How can you possibly feel secure about her boundaries when you can't tell from week to week where they are? It's almost guaranteed to foster insecurity.
