See, this is why I really do feel you are not understanding what you need to be doing.
Everything you do seems to revolve around what sort of progress you may be making with your W. Since that is ALWAYS your focus then you are halting any progress on yourself.
You keep saying she let the D go. Yes, for now she did. As much as I hate to say this you need to think of the worst case scenario as to why she let the D go. It will help you detach. Lets say she let the D go for her financial gain. You will have more income this year and she might be losing her job while you may be keeping yours. So, she lets the D go for now so when she does file she wont owe any support and actually may be able to get support from you. Or, lets say she is shopping around for something better (another man) and knows you will sit around and wait. If nothing better comes along then maybe you are her fallback. Both cases suck but if you think in those terms you will detach much faster.
You are like a detective, always looking for clues about your W and that puts you in a place where you have NO CLUE about you.
Honestly, until you take your W out of the equation nothing will change. Big deal she is not angry anymore. What does she want.. a cookie?
As far as you not wanting to plant seeds in her head about where you may have been going with an overnight bag it just goes to show you want to control what she thinks. Who cares what she thinks? You are a grown man who was kicked out of his house and told you were no longer wanted. Where you go overnight is no business of hers. She can think what she likes and a little mystery never hurt anybody. You owe her no explanation. EVER.
