yes. it can either evolve backwards so that it loses its luster and becomes friendship or worse....hate. Or it gets better with time, changing and deepening. Often times it begins with a love that's built on physical attraction, but evolves into loving for who and what that person is inside. It's put to the test because of the stresses of life, which strenghtens it. I don't think love ever stays the same....it always evolves in one way or another.
