Real, true love, as in love the highest virtue that people often mean when they sincerely but nonchalantly throw around the word as the solve to the world’s problems, is this: To will the good of the other. ( — Saint Thomas Aquinas)
This love is not affection or sexual attraction or security or comfort or lust or mushy-gushy feelings — those things are simply that as named: affection, sexual attraction, feelings, etc.
Therefore real love is a choice, an action. To do this purely and therefore most effectively one must give of themself to another without expectation of anything in return. Of course thus done one does indeed receive.
