This is just my opinion, but I don't think that you should move in with your W for a whole month. That's a long time if what she wants is space to figure herself out. If it was just a week or two then I would say go for it. It's also long enough for your D to adjust to you both being together again and then you're going to split back up. She seems to be aware of when you are both together and gets upset when you're not. If you want minimal disruptions, then moving in with her isn't the answer.
I would keep looking to find something that's more move in ready or try to find a short term alternative. There are furnished apartments that you can get on a month to month basis out there. Maybe you could look into one of those for the interim.
Just my opinion, take it as you will.
Peace, B
