The two split in July after Stewart, 22, cheated on Pattinson with married director Rupert Sanders.
However, the two have reportedly reconciled their romance and are seeing a psychiatrist to help them rekindle their romance.
According to mirror.co.uk, the first advise they have received is to sleep in separate beds for at least a month while they "work on communicating, healing wounds and trust exercises".
"Sex is going to have to wait. The plan is that the two of them concentrate on each other and rebuilding their relationship. It has been a tough time for both of them and the psychiatrist has made it clear that this is going to be hard," said a source.
The psychiatrist also insisted they take a romantic break away from the glare of publicity. And they're clearly following his advice after booking a luxurious Brazil hideaway in the heart of the Amazon rainforest.
