what is love? I think is the biggest question. I think we should all look at just one point. Always look at whether your love has the positive factors more or the negative factors. And also think whether the positive or negative, which factors about your love are more dominant over the other. If the positive factors are dominant, never let go of your love and if the reverse, let go of that love, as it would only give you unhappiness. This is all you have to implement in your love, and then you can always be sure whether to love or not to love. As when in love, be loved but dont love and not be loved, as some day u will be loved the most, by the person who will be your beloved.
