Joshua (the computer) invited them to play a game. "Let's play Global Thermonuclear War".
In the end, the computer makes a comment about these 'War Games'.
He says: "A strange game. The only way to win is not to play the game".
Your W is inviting you to her game. It's called "Borderline Personality Disorder". In this game you CHANGE THE RULES EVERY DAY. So learn something from Joshua. Don't play the game.
Play your game. The one where you look at her with sadness, and a little pity, because she is broken and you cannot repair her. Only she can do that with Gods help. When she chooses to.
Until then, stay out of HER game. YOU can't win because she changes the rules if you START to get ahead.
Have you ever seen the movie "Madagascar"? Remember the psychotic penguins? They think they are undercover spies.
Whenever they are around people or animals who they don't want to betray their 'secret identities' to, the 'skipper' always says:
"Just smile and wave boys, smile and wave"
or
"Cute and cuddly boys, cute and cuddly"
That's their way of 'blending in'.
I guarantee that from now on you're going to think 'smile and wave' from now on whenever she starts going of and being crazy. Do your best not to laugh at her, but be sure to smile. I wouldn't wave though, just do it in your mind. If you really wave she'll think YOU'RE nuts.
And remember what Daffy Duck said a long time ago: "You don't have to be crazy to do this, but it SURE HELPS!"
Be the Alpha male in your clan. I know you are this man and I have faith that you will come out of this stronger and better than ever before.
By letting her go, you give her the gift of learning what life will be like without you. She needs this because she just doesn't understand that even with the blemishes, you're one of the rare men who exist out there that have real morals, real commitment, real unconditional love. She doesn't understand because she really has no true example of this from her childhood so she has nothing to compare against.
For her, this is the hard lesson. We'll all pray that she gets it.
