Impossibility

What do you do about impossible relationships? Actually, what can we do about them? After a point, things are really not in our control...or are they? I wonder, to what extent is our turmoil a function of our own actions? F says that we just don't listen to ourselves...maybe he is right...in this mad cacophony of noises, maybe the voice of our heart is the first victim...but what if the voice of your heart is likely to lead you down a path that you know you should not embark upon...? Does denial become an accepted and rational option is such cases? Maybe not..because experience (and to a certain extent cynicism) says that denying something for too long might give negative returns in future...and that too with a heavy premium...I know that this confusion is not likely to go anytime in the future...I only wish that like mathematics, everything in life had a logical conclusion...or at least a conclusion...because I know that not knowing is what ultimately kills us all...
