Love, even romantic love, breaks down conceptually into a combination of affection and charity (though romantic love has a sexual component and feelings of deep passion). Affection breaks down into liking and appreciation (which is evaluative, whereas liking is felt) and a desire for the good of (if you question this, ask yourself whether you can have affection, including liking and appreciation, without having a desire for the good for someone or something). If you desire the good for a person, like them and appreciate them, and these are genuine, then you have affection for them and will do charity to them. This is what it means to love.
