A friend of mine was cheated on. He felt devastated. He questioned his worth. A rabbi-friend advises him: she cheated on you.....That sucks.
and - free unwanted and unsolicited advice from you friend.
your depth and goodness is independent of her.
so while there is hurt - the wounds of love.
there is not the searing pain when your very existence and value has been called into question.
that stems from you decency - integrity - compassion - and divine image realized in her life.
nothing she can do can touch that.
