Yea for you getting out of the house!!! It might not have been as exciting as going to Vegas or something- but like you said, you GOT OUT so give yourself some slack.
As far as the homecoming...that's a tricky one. Its seems that you have already written a scripts as to what is going to happen... try to have no expectations. Fact is, she hasn't told you to move out yet, so this is still your house and you have every right to be there. I can understand how scary it is to not be able to predict her actions at this time (because like 2thepoint said she is an alien right now) but you can control *your* actions. Only you can decided what you will be comfortable with for her homecoming. The ideal setting would be something like this: She comes in the door and sees you dressed nice and you're gathering up your things. Then you leave shortly after she gets home and say: 'welcome back' as you close the door behind you. Stay gone for a few hours (go the movies if you have to kill a couple hours). You come back and greet her with a smile. Don't ask her about her trip, pretend you have something else to do in the house (it would be awesome if you could even make a phone call, that you have to leave the room to talk-hehe.)
Now this does a couple of things: She is left to wonder where you're going looking all dressed up, she can't immediately confront you about moving out (if had any plans to), you have showed her that you created a life while she was gone and that you weren't sitting around waiting for her return. When you get back, she will have had time to wind down from her trip and whatever plans she had to confront you, will have gone from emotional brain to logical brain- and the conversation will be much calmer (if there was even going to be one).
Just my 2 cents I really appreciate all the support you've given me on my thread.
