Free love for the win. I wonder what'll happen to exclusive relationships when money ceases to be a thing. Personally I think it's the economic forces of the world that's forging exclusivity for intimate relationships. Like, marriage was something done during ancient times to cross-consolidate regional powers and more often than not, for monetary reasons. Emotions are so fleeting - an ex used to tell me "if it doesn't work out, just remember we had our good times.".
Although on a personal note, I kinda find cheating inexcusable if one enters an exclusive relationship with another - and in this case, love without sacrifice is like theft.
But, Love is an emotion and like all emotions they're meaningless.
Love for me is "extensionality", the other person being an extension - a better half, significant other as some would say.
You both guys are right I see !
