No one is backlashing you. We are pretty kind hearted here. I think the previous owner did a disservice to these snakes by keeping them together. BP's in the wild and usually in captivity are not kept together. They only come together to breed. That has nothing to do with you.
The choice is yours on what to do. You can keep them together which does create stress for them. Another thing to do if the enclosure is big enough is to put a divider in the middle and create 2 enclosures. You can still breed them if you wish.
The choice is ultimately yours. We do have so many experienced breeders and hobbiest here with a plethora of knowledge willing to help you with whatever you decide to do.
