There is no more sadness only because
1) you have tried ur best
2) Best means there are no remnant "what ifs" or "I could have tried harder"
And when you see no need to ask yourself such questions, then you will only feel joy and peace.
of course, there is still the missing, but no sadness or regrets.
What I have learnt is that if you know that you hardest best is not good enough, then it's time to let go... and let God!
Learning to live my faith, and understanding the world of multiple "blind dates".
What's there not to love about making more friends? :)
