how much time Love can live???

to me certain types of love is forever, there's no getting around saying you can't love a child sibling or any type of family member unless they have done something terrible to you. For someone you are no where near related to it depends... i find people mistake lust for love and that does go away, but love itself, that's something hard to die down, even if you don't feel the exact same about the person that you are with. I know there is one man I loved and I still love him, not the way I use to of coarse, because I don't want to be crushed with reality that he didn't love me back. but deep down he has a place in my heart.

if its true then its throughout life else unitil u get physical contact
