I don't think there's much we can do to prepare for a blow like this, especially when it's done the way your W & IK's H handled it.
I'm not sure on the moving back in idea. I know I said earlier that it might not be a bad idea, now I'm not so sure. Some feedback from others here might help to get some clarity.
When I talked to you this morning, you said something about your W still asking for a backrub the night b/f serving you. That doesn't seem to make sense, although she sure seems to have her own unique way of communicating.
