The way I do it I literally wait until her tube is dropped fully and introduce them again. She will lay within a day or two. Another way is just put a pot near the divider and they can breed through the divider if your worried about health.
My female got beat up the first round of breeding. Second time I didn't even remove the male they're fine.
Let him spray thru the divider?? Or put pot under divider for both to access??
