Welcome Kara,
Nice camera, the GSN.
Now to help feed the forthcoming GAS attack. Let us start small. As the GSN has a long shutter release stroke a "Softie" soft release is an ideal addition to your equipment needs. Check this link:

look at the soft release, only $10 shipped. Choice of colors available also, better buy 2, each a different color so that you can tell which camera has B&W film and which has color film in it by the color of your softie.
Since you now have two softie releases and only one RF camera, better start shopping for another camera. A black Yashica GT will go nicely with the GSN.
After using an aperature priority camera for a while, the call of full manual operator control will slowly creep in. Hmmm, a nice Canon QL-17 G-III should just do the trick. Then there is the Olympus RC it is so cute, better add one of those.
Standard 40mm to 45mm fixed lens are nice, but a body that would allow wide angle and telephoto lens to be mounted would really be nice to try. Since you are close to Canada I would recommend a Canon P. That way our friendly moderator will have another allie on his team
🙂
You may want fiance to find a second job real soon, right after you handle a Leica M2 at the local camera shop.
That should be a nice blueprint to follow. Then there are the medium format folders, 1/2 frames, big honking 6x7 Koni-Omegas, even bigger still 4x5 Speed Graphics and Crown Graphics. You can keep him busy and broke for several years.
