I hope you have a blast! I think let it all go for while you are gone. Take the time to breath and not walk on one egg shell or maybe stomp on all of them! At this point, you are doing everything you can be doing. And if you really get to a point where you want to point blank ask her "What's up? S**t or get off the pot..." that is up to you. Only you can make that call. But I understand you get to a point where you are ready to ask that question. BUT make sure you are ready if she says I want to leave. But for now, forget all of that and enjoy your retreat.
