Some Relations:

Opposite (minus) of love = hate
Opposite (minus) of liking = contempt
Opposite (minus) of interest = ignoring
Ignoring = perfidious negation, scorn (not pretended), “killing in installments”.
Immature people are not able to love and yet they do have love relationships and are very passionate, at least in the beginning.
After that they leave their partner, breaking his heart.
A broken heart is a widespread and common condition of our civilization with complementary bad consequences
for the health and quality of life.
Over 90% of illnesses are of a psychosomatic origin.
It is often a short-term or a long-term consequence of an unhappy love.
