I wouldn't really call it a strange place -- I was there too for awhile. Dating from two separate homes but spending most of our free time together. My XWGF absolutely needed to have her own space for awhile after we were back together - it was a non-negotiable. And, it was a good thing. It gave her time to get comfortable and trust again. She eventually started staying more and more nights at the house -- and soon, just moved back in and got rid of her place.
