Keeping yourself busy is the best thing to do. I know you were conflicted about going dark...I think it is up to you, but if there is still a little glimmer from her side, I would probably throw a quick text her way every once in a while. But a closed comment..."Have a nice day". No questions. And don't expect a response or you will get yourself really upset if she doesnt do so or do it within the amount of time you feel appropriate. I am new here too and I am at the same point as you...my WAH dropped the bomb on Christmas day...nice, huh? So I am no expert.
