“Love is a serious mental disease.”

At least that’s how Plato put it. And while anyone who’s ever been ‘in love’ might see some truth to this statement, there is a critical mistake made here. Love is not a mental disease. Desire however is.
If being ‘in love’ means our lives are in pieces and we are completely broken, miserable, utterly consumed, hardly able to function, and willing to sacrifice everything, chances are it’s not love. Despite what we are taught in popular culture, true love is not supposed to make us like drug addicts. And so, contrary to what we’ve grown up watching in movies, that type of all-consuming obsession is not love, it is the manifestation of one’s lower, vain desires and lusts. - (credit to original writer)

A loving relationship is one in which the loved one is free to be himself - to laugh with me, but never at me; to cry with me, but never because of me; to love life, to love himself, to love being loved. Such a  faithfull relationship can never grow in a jealous heart.
