I just don't get it, either. My W has never deployed since having children and has only really been away for a few short TAD's. It really is unfamiliar to us. Even though she really loves them, it almost seems as if she is unfazed by being separated from them. I hope that is not the case. Maybe she talks over that with her own counselor (she is currently having sessions with two counselors).
Maybe she is just dealing with it in her own way. At this stage of the game, clearly our spouses are not likely to share confidences with us, so I don't think its unreasonable to think she might be hurting over the idea more than she expresses. Hopefully that's the case. Or maybe she is just too caught up in her own feelings at the moment that it doesn't allow the loss to actually sink in. If she actually moves without all of you, perhaps that might even serve as a wakeup call that will make her more amenable to working things out. I have to believe at some point they will wake up and see things for what they are are.
