Answer
He may be acting out because he is in pain.  I would highly recommend you take him to the veterinarian for an examination and possible x-rays or blood tests.

In the meantime, I would keep the two separated.  You can try Comfort Zone with Feliway diffusers around the house and try adding RESCUE REMEDY to the water to see if that helps.
