in reply to @briankj I understand. Is it possible to keep a closer eye on her when out in public? I am not going to suggest a leash, although that did enter my mind when I saw your post. Those trackers are not foolproof, as my brother in law has been "lost" on more than one occasion. They can be useful as long as the person does not "lose" the tracker, if you are talking about one of those devices. On the other hand, the iPhone is good for location sharing which might be helpful, assuming your wife can hang on the cell phone, which my brother in law could not. If I were you, I would ensure you are with her at all times so she does not get "lost." I am so sorry that this is happening to you.
