My wife tried it in a pool in Maui... and decided she would get certified... first class turned out to be on the beach ending in an OW dive to 40' while the instructor/photographer spent his time taking pictures (for a price) of the tourists.
That was a long time ago.
She wants nothing to do with scuba.
On a happier note.... she is 100% in favor of me doing all the diving I want as long as I don't impose upon her to ever try it again. We are both very happy with this arraingment.

Now here is something I have notice during my years diving:
There are plenty of folks who are torn between fear and joy when it comes to diving. They like diving and really do enjoy being UW but their enjoyment is seriously impacted by their fear.
If this is you... may I say that confidence should come from competence. If you are incompetent then it is a good thing to fear rather that have the false confidence of nincompoopery.
But fear should be displaced with confidence through training and the
gaining of skills. Gaining certifications will do nothing for you. There are plenty of phobic instructors, DMs and what have you.
Get
skill... with it will come
competence and
confidence.
