Good post CityGirl, I think your articulation "hit the nail on the head"
SD, as you know, detachment takes time. If the tools analogy works for you think of it as working on a woodwork piece. At this moment you are shaping the wood with coarse grain sandpaper. As the object you're working on takes shape you'll tone down to finer grain paper until the work is complete.
Expect setbacks and work on controlling them. This is why I told you to look at being deployed and far from home as an advantage. Because you are removed from her daily influence you are able to cope better. This will change when you get back - be prepared for a minor "crash." The more you work on detaching now, the less impact your return will have.
You're doing well.
