Why do we have "broken hearts"?
Everybody has had them and not getting into to details I've harbored one for quite awhile now. For what reason do we get this emotion? I mean we have fear to keep us safe and anger can be channeled into something productive at times but this... I just don't understand why we get this feeling and what the purpose, if any, there is for it. If anyone has the psychology behind it and maybe a scientific reason for why we as a species have it would be greatly appreciated. Thanks
