She was not yet my "dive buddy for life" at the time she decided to learn scuba, but rather we were still dating, and she thought maybe she could share my hobby. When she casually mentioned on the phone that she planned to take the OW course I replied something like, "That's great!" and not much more. We spoke and emailed a few times, and each time she mentioned what was going on with her course I replied similarly. In other words, just listening to what she had to say. (They love it when we just LISTEN, don't they?) I made a point not to offer any words of wisdom, advice, attempts to solve problems, or anything of the sort, and as far as I recall she never asked for such. In my mind, it would have been okay if she had taken the course and not enjoyed it and/or not done well. It would be NICE to share the scuba hobby, but not necessary--we have many other activities we participate in together, and she has at least one--tennis--that I don't participate in. So, I think the key was keeping my own hopes and expectations in check and just sitting back and waiting to see how it turned out for her. Well, one day we were chatting and she mentioned she had passed the course and, moreover, really enjoyed it. That was nice.
