Ok here's the deal, the snakes need seperate housing, can you house them together yes, is it wise no.

The first snake you own still has signs & symptoms of a RI.
The male snake should be in quaranteen for at least 30-60 days before being keep in the same room with the female.

Unfortunately you do not want to take any of the advice you have been given.

Your older female snake will dominate the younger male, he will become stressed and probably stop eating, and he stands a chance to develope a RI from being exposed to the female that still has a RI.

Please don't get any more snakes
