It sounds like things might be calming down just a tad. I know how heartbreaking these things can be. I have been there. I have found that once they stop trying to chase or tear one another apart that one way of easing tensions is to play with the both of them. Take a toy like a feather on a stick or something and get them to start playing with it. It has worked with mine a few times since they start to focus on something other than each other.
