Otherwise, the one promoting the separation should admit to self and spouse that the ultimate goal is divorce.
People tend to deal better with a harsh truth than a supposedly sympathetic lie.
While attaining that time out sounds like a good idea, typically it is not. Because once they experience the relief, it is difficult to go back into the unpleasant task of figuring out how to solve the problems.
However, the goal for those separations is not necessarily to save the marriage; it is to save the person.If your husband can prove that you've committed adultery (and, remember, it's even adultery if you've already separated), you could be prevented from asking for spousal support. Would it upset them to have a new person around so quickly?
