does any relationship is necessary to love someone?

When I say x = 3y, x has a relationship with y but they don't love each other. When you punch someone without any reason in a bar, you'll have a negative relationship with that someone. The word relationship doesn't always mean you love them, it means you're somehow related to them. Although today it always means that you love that someone.

Hello ranjanamishra :) Relationship is really not necessary in loving someone. Family, relatives, friends and new found friends can be enough. But sometimes we are looking for a partner that would make us happy and feel contented. We need a lifetime partner that would accompany us till we grow old.
