JS, I've written extensively about the LBS that is physically separated vs the LBS that is still living with the WAS.
Both think the other has it better. And in reality both have advantages and disadvantages.
However, I would argue that if you are having trouble detaching, then you will have that problem whether you live with her or not. The imagination is a powerful thing. Look at OrangeK's threads. He was forced by a PPO to have no contact (except for directly related to child care), yet he still struggles mightily with detachment.
You need to throw yourself into DBing. GAL like a madman! Those that struggle the most with detachment usually aren't doing enough GAL. Staying busy is the key.
