How old are you? You are small, and that's not an astoundingly low RMR for someone your size, depending on your age. There's simply not that much of YOU to burn calories.
Yes, it is true that for either losing or maintenance your choice is to move more or eat less, or both. Moving more, building more muscle mass will eventually raise your RMR. One of the great things about strength training and cardio is that you'll burn more calories for a few hours (up to 24 depending on how you push your body) after you finish working out. If you exercise less and eat less, you may stay the same scale weight, but your body composition will change and you'll end up relatively fatter and larger. 117 at 19% bf looks and feel a lot different that 117 with 26% body fat. Yes, the scale number is the same, but it's really all about what you are made of.
From the sounds of your post, I'm inferring that you've pretty much reached you goals
You must feel and look great!
To stay that way, keep doing what you've been doing. Or change the intensity and variety of your exercise. To maintain what you've achieved, you still need to workout. Just eating less won't keep you fit
