I went through this same dilemma with a GF a few years back. My opinion, and that's all it is... Is to have her ride behind you at a safe distance and do what you do. Use turn signals, hand signals, and even budget for a blue tooth communication system to directly communicate with her. Now, with my wife, who wasn't that GF, she and I ride our bikes, we talk when necessary. She and I both have been riding all our life since we were kids. I can alert her to road hazards, road surface, traffic slowing, what my intentions may be, speed, etc, etc. There's a lot going on and until we hit the backroads, we are chatting.
I've lead group rides on many occasions and I pair the bikes turn signals and brake lights with extensive use of hand signals with braking, turning, slowing, passing. I want the rider or riders behind me to know as much as I do of what's coming. Using my outstretched leg to indicate debris or animal carcass, pile of leaves, gravel, etc, etc.
As for her riding in front, I tried that and felt out of touch and out of control of what an inexperienced rider may encounter. Muscle memory suggests and indicates what we may or may not do in a crisis, panic, obstacle situation and their instincts may prove to be wrong. Follow me, do what I do.... I will guide, you help you. You want a positive calming, helpful style to ensure she wants to do this again, again, and again. It's a wonderful thing to have your best friend, loved one ride the ride with you....
Good luck, happy riding.
