Your perspective is in error - she is not your friend!!! Friends don't let friends put a penis in them!!! She was you hor and you were her pimp - but only for a season, as all pimp/hor encounters are!! She now found a new pimp and you have not found a hor to replace her - and thus your anguish!!!
Don't compete - hors will always find a willing penis faster than a man will find a willing hor !!!
