I am sure that your wife will get the bug,,, if not in the pool, then when she does her first open water dive and sees everything you've been talking about all these years.
I am a warm water diver as well so guess we will have to find a place where the water temps are in the 80's... shouldn't be too difficult!!
I tend to get seasick on LOB but wear a transderm patch the first day or two until my sealegs kick in and then I"m fine.
