From unknown to farewell

The best of friends
They said they'd always be there
Never tell each other a lie
Never think against each others will
It came to pass she falls in love with his best friend
Though upset he was it soon passed and his approval remained
He helped through hard times
When his best friends fought
Reviving their love
When most though it was dead
Yet lies and deceit soon leaked through
From all sides shes bombarded
False tongues with lies were provided
And then a letter
Unanimous the sender unknown
Return address unreal
Brought out the couples inner most fears
And soon this fear turned to blame
Hoping to find the senders name
She turned her attention to her former friend
Said that all of it.. it sounded to much like him
It crushed his heart that the couple who he helped so much
Would turn against and believe the lies
But as simple as it started it now was over
Too much hurt was poured on by her mouth
And soon unknown became farewell
