Glad your experience was rectified by a better instructor. As an update she went with me to our local Scuba shop anniversary event and has registered for a private DSD plus swim lessons. I was just wandering around the shop when I looked over and saw her deep in conversation with one of the instructors. I think she is going to be fine. I just really needed to not be in the middle, LOL.OK, everyone is different but I will tell you my story:
For many years I wanted to try scuba but was scared. Finally about 10 years ago on vacation I took a try scuba course and had a very bad instructor. I was basically left alone in a pool while he watched in the morning and then took my out to the open water in the afternoon. When it was time go into the water I just couldn't do. I told him, I'm sorry, but I just can't do it. He said something like even little girls can do this and eventually pushed me into the water. Next thing I know I'm going down and I just kept telling myself to keep breathing. I started to calm down but we reached large drop and all I saw was darkness below and could see my instructor. I really panicked. My instructor came over and tried to calm me down but just kept shaking my head no. Upon reaching the boat he told me that he was afraid I was going to hyperventilate- I almost used up a whole tank. I had nightmares about the experience for a long time.
Fast forward to a few months ago. I talked to a local dive shop and explained my experience and said he I want to try again but I need to go slow and really understand the dynamics so I have control. I feel a big part of the fear- at least for me- was not having control.
It sounds like she wants to do and maybe her doing it without is better (or maybe you can take the course again with her if she prefers if that is allowed). Personally I would try to emphasize that she will get great satisfaction of doing it even if in the end she decides diving is not for her. I think diving together would be wonderful and an activity you can enjoy together for many year. Then again some couples need their time apart.
Well this was a long first post...
