I think having your WW spouse in the same house is worse. It makes it much more difficult to detach, particularly if kids are involved.
In my case my spouse is there pretty much all the time, and it's difficult to get true separation. I think most of us would agree that it's easier if you are physically separated in terms of detachment.
The other thing I've found is that any time I slip into a prior behavior that caused issues in the marriage, it sets everything back to square one again. The 180s and GAL activities help, but it's a struggle sometimes to be consistent.
Definitely agree with keep posting, read the other threads, there are outstanding pieces of advice and situations that will relate to yours.
Best of luck in your journey through this, we're all going through a lot of the same experiences and our thoughts are with you as well!
