Well, unconditional love does originate from the favorable treats you mentioned, but its also the stories you had with them, your experiences, your ups and downs. Everything that made your life a little more worthwhile by simply standing by your side. Past a point, i believe it is impossible to end that relationship voluntarily, for both sides.

If it was only because for who they are, I dont think your love for them would continue nor evolve, it would be a simple materialistic jealousy, never making it past conditions (hence, unconditional love).
