what's love then?

is it love, if you don't care is it love, if you've just left me there is it love, if your heart is not known is it love, if he's love is not shown is it love, if theres always fear is it love, if it ends after a year is it love, if there's always heartbreak is it love, if the smiles are fake is it love, if you can't see it in my eyes ..and if it wasn't love, why do the same feeling arise those thoughts wraped around me like a cast made of ice the only thing i really know about love, is that the feelings you get from inside is truly nice
