It needs to stated again that jebsurf did the wrong thing. Also, 0-24 dives does not make the op a very experienced diver at all.
Assuming that the dive counts are old, which they usually are, there's a better point: 1000 dives as a diver does not make one competent to teach diving.
Teaching diving as a non-instructor is foolish, egotistical, hazardous, and liability-wise, borderline insane. As is taking a new diver on a boat and making them plan a 100 foot dive even though they are diving in 10 ft of water, which is one of those things that experienced instructors have figured out. After all, four feet of water is all it takes.
Teaching diving to a family member is borderline unwise even for an experienced instructor, which is one of those things that experienced instructors have figured out. Men in general are condescending and paternal to women, which is why I won't even train family members together at certain stages of practice. And I certainly no longer allow husbands/fathers to "come along" for training dives because I got to see too much of how incompetent husband/father divers try and show their student wife/daughter divers how to dive, and unintentionally endanger their loved ones and interfere with their learning.
(On the other hand someone teaching themselves to dive is a completely different thing, since the issues of motivation are completely resolved in that case. Instructors, at least those who are not driven by ego, see their job in training divers as massively accelerating the process of learning diving that most motivated people could do by themselves given enough time, and gear.)
My bad analogy for someone who knows how to dive thinking they know how to teach: Driving does not make one a car mechanic. Getting surgery done to me does not make me a surgeon, flying on a plane does not make me a pilot.
B: have a talk with the instructor and let them know what happened
I know how that conversation would end if I was the instructor. You'd be out the cost of a dive class, and your wife would have nothing to show for having done any of the course to that point, since we do specifically talk in the classroom about what a diving license allows one to do. She might just start 'training' divers herself right after she gets her license too. She does have a boat after all.
If your wife was willing to be peer-pressured into violating the basic rules of diving that she just learned, even before she got her license, she's not ready to be certified.
Which I, unfortunately, imagine she would feel relief in hearing.
