"It seems to me, that if we love, we grieve. That’s the deal. That’s the pact. Grief and love are forever intertwined. Grief is the terrible reminder of the depths of our love and, like love, grief is non-negotiable."

Never seen this before, as a person who has grieved considerably but won't/doesn't read grief literature.

I came to the conclusion years ago that grief is just unexpressed, unshareable, uncommunicable, thwarted love. It's all the love I cannot give, all the words and touches and moments that fail to alight on the one I love but instead, missing its intended, affix me to the void.

So not merely entwined, I think grief is love itself unsatisfied.

From experience I found the feeling of being in love without being loved back, is very close to the feeling of grief for a passed away loved one.

So in summary, both are an excess of love not finding its goal.
