Good idea HWA to apply the 48 hour rule. I personally do not think its such a problem to say that to your W at this point. You have given her heaps of space and initiated no contact for a long period of time, its not like you have smothered her at all. You know, sometimes you have to take that leap of faith, and nothing else has worked so its worth a try IMHO. I did similar, and it did have the desired effect for my sitch. It is a tough one, as long as you are prepared for the worst too.
