BS here, I have had a two moves after separate D Days and can give you my perspective.
The first D Day we were in the process of relocating 2,000 miles away from our home city. I think healing and rebuilding in a new and exciting area (Seattle) was extremely healing for me - we reconnected with all of our new adventures exploring the new city, I didn't have visual triggers of the A (hotels/restaurants they went to), I wasn't scared that the OW was going to follow us, and we had to depend on each other which really helped rebuild our closeness. We also went to some MC and the A wasn't totally swept under the rug (his issues were, but there was some attempt to address the M) It took me awhile to get a job which allowed for some extra free time to focus on the M. In that case moving added to our R.
10 years later we had another D Day and moved out of state 6 months later for his job. This time the move was more harmful the helpful. The A's weren't acknowledged (because he hadn't actually had a full PA with anyone so he was denying and I was stuffing it), there was just major rug sweeping. I was very resentful about the A and that I moved for him and gave up a great job and beautiful home. The only helpful thing was that I didn't worry about him cheating while traveling because he did not travel in this position.
So, now trying to R after D Day #3. I would LOVE to move away. I get bombarded by visual triggers pretty much were ever I go. The OW was in my house and knows where I live. She works 2 miles from him. He's an SA and every time we go to the mall or out to eat I worry that we might run into someone he "knows". Moving would ease my anxiety and triggers quite a bit and would accelerate healing and rebuilding.
