Well after reading the title I had just one thought in mind - such relation could offer just a pure torture to the emphatic individual. Reading further apparently just approved my first guess.

Now the curious question, what do you think happens when an emphatic person is ultimately hurt, gets tired and has enough of the abuse? Reason might be not just the bad relationship... but also because most human's nature dictates them to abuse a help given and treat the helper/healer (emphatic people all in all) as weak... they take all she/he has to offer and leaves the person emotionally and physically exhausted... drained.. over and over again... what happens then?

All in all good read, I really enjoyed it.
