Big picture I'm sure it's far better to have her under the same roof while we're going through this, but part of me wonders if it wouldn't have been easier for me to detach consistently if we had been physically separated. That's pure speculation. I'm not about to suggest it.
Interesting question. In thinking back, I do think it helped me that my wife and I were separated and living in two different houses during the first part of our piecing. We "dated" each other for awhile, and then she started inviting me to stay over, and then pretty soon I just moved into her rental house and we let our daughter rent out our house from us because she and our son-in-law needed a place to stay. Now that I read your post, I'm remembering times when it was probably good that we each had our own place to go back to.
