It probably wouldn't hurt anything to leave the male in with her. Some breeders leave the males in with the females until the females lay, just to be sure that they don't miss a breeding season, and it doesn't seem to harm anything.
But something to think about is that ball pythons are solitary in the wild, which is a good indicator that they would rather be alone in captivity too.
Nobody is trying to criticize you or say you are a bad pet owner. On the other hand, it's pretty unkind of you to imply that there's anything "unnatural" about breeding snakes on purpose, or that we care more about the money than we do the animals.
If you ask a question, be prepared to get answers you may not like. I learn new things about ball pythons every day, and I have been researching them for over three years now.
