I'm new to mountain biking and have also experienced some of what you allude to. What I've found with mountain biking (after years of road riding) is that there is so much going on to attend to at any one moment that actions I take on road bikes with ease can be more difficult. On trails, there might be roots, rocks, trees in the way, sharp turns, loose sand/gravel/washout; and at the same time I am trying to negotiate gears. If I stop, even getting clipped in (I use clipless pedals) with my second foot can be challenging as I am often bouncing all over the place while trying to do that, rather than smoothly coasting along as I am on a road bike. Sometimes I too avoid shifting just because there is so much going on that I need to pay attention to that I can't manage the shift (especially upshifts in the front, same as you) at the same time as I am turning, braking, getting out of the saddle, avoiding obstacles, and trying to stay upright!
However, I find that I stay mostly in the middle ring, and that helps a lot with the chain issue that bothers your fiance. I shift up and down in the back as needed, and I try to only go into the inner/granny ring on long climbs. Normally I can see those coming and anticipate and shift down in front before I run out of gears in back. On short, steep hills, I power over in my middle ring. Since I stay in my middle ring a lot more, I don't have to deal with getting back to it from the small ring as often as you do.
So perhaps you could try riding in your middle ring (stick with the larger/easier cogs in back so it doesn't feel very different from the inner ring) as much as you can versus your inner ring. I don't know if this will help, but I thought I'd throw it out there.
One other thing that has been helpful to me is occasionally riding alone. If that's possible for you, you might want to give it a try. I find that I can work on my skills much more effectively when I am not trying to keep up with someone else or talk to them. I feel like I get faster going with others (since I push myself not to fall behind more skilled riders), but I improve my skills more on my own when I can actively PRACTICE specific things. I had one trail ride, for instance, where I actively practiced clipping in with that second foot. I stopped numerous times and had to clip in again. Since that ride, I have had a much easier time of that particular skill.
Good luck! And don't feel bad - mountain biking is definitely a challenge compared to road riding! I wear a heart rate monitor, and find that my average HR tends to be about 10 beats per minute higher on mtb rides than on road rides. So yes, we are working harder!
