All relationships are karmic. This one is nothing more special than any other.
And you most probably have to learn something if you still cannot heal.
I always advice people with heavy scorpio energy to not try to move away from it or run away from it, but simply accept it as it is and let it die. Mourn it, but accept it's over. As painful as it is, it heals and brings closure.
And again I don't know which chart belongs to who.
