I agree that it depends on the situation, and which version of our spouse we're getting that can make a same house DB attempt fruitful or futile.
If your spouse is buying new lingerie, tanning, dieting, leaving for days at a time, locked phone, new passwords, and still trying to deny an affair, its possible its just too much to handle.
For other people, natural DB'ers, its amazing how they can just tune it all out. Every situation is different. And of course each person needs to decide what the need to do for themselves and their sanity.
