I heavily agree in getting her involved.
I highly recommend having someone that isn't sharing the same bed with her teach her. Which eliminates you, the UPS guy and most of North Vancouver, from what I hear....
Seriously, this isn't a shot against you or your GF, but more often than not, any frustration in the game usually gets directed towards the person teaching. And, your GF has a way of "listening to you" and "listening....to you". She hears what you say, but her interpretation of what your saying will be different than if it came from a thrid party.
Harvey Penick once said that that he would never try to teach his wife to golf as long as he lived. And he never did. And he's one of the best teachers to ever show another how to play the game.
I've played golf with my GF in the past, and been to the range. But, i've never offered advice to her unless she's asked for something specific. "How come the ball goes off to the right?"....."Well, there are a number of things that could be the reason.....but for now, try and get the clubhead catching up with your hands. That should do the trick."
I guess what I'm trying to say is tread lightly. Golf is such a frustrating sport for those that are naturals let alone those that struggle.
And sometimes that struggle can bite you in the ass. Luckily, I have no experience with that, but in all my readings, more often than not it's recommended to get a 3rd party involved.
And I don't mean your hot neighbour.
