If you are having doubts about the A, and if she has not volunteered anything to make you feel better, then I suggest you not paint yourself into a corner before getting it settled.
You have already slept with her and was so excited over last weekend, but the status of the A is unknown. If you allow her, she will ease her way back into the house with no further discussion about it. If it were me, I would probably need some assurances. I mean, if she can be so bold as to say she wants a week's vacation with you to see how she feels......you should be able to tell her that you need to know....before taking the vacation.....some answers to your questions regarding the A. If she gets angry about it or refuses to tell you, then accept it as a very bad sign.
I do not think it would be wise for her to return to the house or to take a trip until she gives you some basic information. That is the very least she could do. But the longer you let it ride, the tougher it will be to find a time to bring it up. You either are either looking for a better mood, or you are having a great time and don't want to spoil it.
Scaring away the squirrel is when you smother her too quickly in your attempts to get her home. The LBH often will take the first move she makes as being the green signal that everything is going to be okay. However, she may still be dealing with her issues and needs more time and space......and take it slower than the man wants to go. But I would put giving you an honest answer about her A as being in this category of scaring away the squirrel.
You don't want to be deceived until she gets back....and then she goes back into her distant & cold ways again. That is why I was encouraging you to take things slowly and get those biggest issues resolved before she comes back. People look at having sex differently. If it is needed in order to heal and work through your problems, I guess that is up to the two of you. It just might be a little tricky to know exactly where she stands if she's not talking. Know what I mean? It may make it harder to bring up unpleasant topic.........or not, IDK. You have to decide that part for yourself.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
