Recently, I noticed a quote stating that “The opposite of love is not hate; it’s indifference.” This quote is often attributed to Elie Wiesel. Quote Investigator (QI) found an “earliest close match in  “The Beloved Ego: Foundations of the New Study of the Psyche” by prominent Austrian psychologist Wilhelm Stekel”.
“There is no love without hate; and there is no hate without love. The opposite of love is not hate, but indifference; the opposite of feeling can only be the absence of feeling. Disinclination, which is coloured by feeling, often only serves the purpose of concealing and protecting oneself against an inclination. Love and hate must go hand in hand; and the people we love most we hate also, because hate is grounded in the nature of love.” Note: bold marking in quote added by QI.Excerpt from “The Beloved Ego: Foundations of the New Study of the Psyche” by Wilhelm Stekel
The above would result in the following diagram:
I had some trouble finding the rational opposite of (emotional) love but I ultimately decided for using the word ‘caring’ as caring is long-term, similar to indifference. Nevertheless, some ‘indifferent’ people will start caring for their estranged partners in dire times (eg, terminal sickness).
I suppose that things are much more clear for me now.
I, I loved and lost
The same as you
So you see I know
Just what you’ve been through
And if you’ll let me
Here’s what I’ll do
I just have got to take care of you
