Greek had a few words for the English equivalent of love...1) agapey - decision, selfless, self-sacrificial, desire for good 2) phileo - friendship, care 3) eros - sensual love, arousal, emotional passion
People today make the wrong choices, and base their love on feelings... on number 3... love isnt supposed to be about feelings, nor friendship...that is subjective... love is supposed to be about objectivity deciding to be loyal, to honour and cherish someone, to respect someone.
As supporting evidence, divorce rates are spiked in relationships where both partners have had intercourse with other people outside of marriage...but divorce rates are greatly reduced where both couples have had no prior dating realtionships nor sexual relationships prior to marriage...and it is not to do with sex at all...but to do with the willpower and psyche...the mindset if you will...that a person is supposed to self-sacrificially fill a single responsibility of a relationship with no other concerns in life... it is the objective love that is also described for people who take care of their own babies, or die for a cause...it has nothing to do with passion
If you want any references I can google it for you or help you...but do not worry...real love is an objective decision, that one makes inside onces core... it is not a transient feeling... alexithymia does not mean you dont love someone...just means you are not subjectively emotional, which is somewhat irrelevant to a successful marriage anyway...the feelings disappear after the first few years...and what carries you after that is the desire to protect and nurture
