  Detachment, on the whole & in the long run, is perhaps a good idea. I say 'perhaps' because there are times when doubt creeps in. In relationships, it always makes us the needed & never the needy, so much so that there is no or very feeble yearning in us to reach out, that separation does not make us bleed and that unions make for joys lackadaisical and ephemeral. It makes our memories, of happiness and sorrow, blurred.
