My wife was a non-skier as well, and never really enjoyed skiing. I got her private (and group) lessons at Beaver Creek and Deer Valley -- fine ski schools. But there was no love. We even had a serious powder day at Vail on one trip -- and she had a bit of a breakthrough... but still no love.
BUT.. as an ex-competitive figure skater, a friend suggested skiboards/blades. Kinda like skating - but with release bindings. I bought her boards similar to these:
Twin tips. Perfect for bumps. Great for backwards skiing with the kids. Not suitable for powder more than 6-8"... but she went from reluctantly tagging along to be with me, to shredding the whole mountain (except on deep powder days - too short!).
Blades (Boards) got a bad rep at first because they didn't use release bindings. But now real bindings are more common.
They require a slightly different technique, because they are 90cm "fat twin tips" --
Skiboards (blades) was the catalyst that got my wife from ambivalent to "in love".
Hope this helps.
