Bsb, it is a marathon, not a sprint. You checking every 5 minutes if she's come around is BAD for you, very bad. You have the scale of hours and days in your mind, but it is more like months and years...
You letting your W go is mainly for you, because (as you are seeing right now), she does not give a rat's ass about you. And that is normal, and perfectly ok in this situation. You have to go forward with your life, do not allow yourself to get stuck waiting for her. She may come around, and then again she may not. We are all in the same boat. I am about 2 years ahead of you, so things are a little clearer for me. We all thought that our spouses were the exception to the rule and that they will come around in no time. Sadly that was not the case.
Soon you might come to realize that this whole mess you gotten yourself into is not all bad. This is a great opportunity for you to grow, to rediscover yourself and live to your full potential. It is not an accident that Cadet said at the start of your DB trip that you have been given the gift of time. You have, and use it wisely...
By all means do test the waters with your W, just do not get your hopes up, as it could be another mini BD. And lord knows it is the last thing a LBS needs.
