"My love for Linton is like the foliage in the woods. Time will change it, I'm well aware, as winter changes the trees - my love for Heathcliff resembles the eternal rocks beneath - a source of little visible delight, but necessary. Nelly, I am Heathcliff - he's always, always in my mind - not as a pleasure, any more than I am always a pleasure to myself - but, as my own being - so, don't talk of our separation again - it is impracticable..."
I find, more often than not, someone has already said what it is I've been trying to say.
Truly though, it is impracticable.
