Yo Bada-Bing,
Here's the long answer that Commander Grinder warned you about. lol:
No son, DON'T DO IT. This woman has obviously demonstrated a consistent LOW interest in you. Confidence, although it can be mysterious, it is NOT entirely invisible.
What I mean by this is that people can always SEE evidence of how you feel about yourself if they have enough exposures to you. This chick has obviously not been impressed enough with you at the level of confidence that you have already displayed----DON'T show her anymore evidence that you think so highly of HER to your OWN detriment.
Sending her a letter of well-thought out, logically written observations that she will INTERPRET as ultimatums will NOT help your cause. Women, if they are to remain attracted AT ALL, must see or feel confidence all over you when they look at you OR think about you. Follow your OWN intuition AND Commander Grinder's advice in this situation, soldier.
Sending her this letter will most likely either fall on deaf ears, be glanced at with blinded eyes, or WORSE----be used as a trophy of war by this woman (who you should basically think of as a deserter or your enemy at this point) to show to her friends proof of what a LOSER you are to her.
And NO, Bada-Bing...i'm NOT calling YOU a loser, my friend. Quite the contrary, I think you're just another guy who took an emotional hit from a woman that you allowed yourself to get too prematurely and undeservedly attached to. It HAPPENS man...
So all I'm doing here is just painting the harshest picture that I can of how very inconsiderate some women (and PEOPLE in general) can be towards you when they AREN'T into you.
So I say, follow your first mind (as they say...lol):
Continue to journalize your Babe Missions if this continues to be a good way for you to excavate, analyze, and learn from your experiences----but DO NOT ever send a ONEitis-type babe anything written that she can use against you----hoping that she will read it and have a change of heart or a revelation of your worthiness.
Most of the time, this DOESN'T happen. In my tours of duty on the dating/relationship front, I've found that most people only change if they have a stronge enough reason WHY. Translation: If they feel that by changing it will selfishly benefit THEM.
Otherwise, I suggest that you go by the Victory Unlimited Female Interaction Model:
Most times, it's not necessary that a woman sees THE LIGHT (agrees with me), but only that she feels THE HEAT (suffers the consequences for NOT agreeing with me when I KNOW that my motivations are in the service of defending the lines of RESPECT between the BOTH of us).
So put your thoughts on paper, but keep your journal TO YOURSELF. She doesn't deserve any further insight into your soul. And even if she took a look into it, at this point, it's obvious she wouldn't appreciate it in the manners in which you seek.
March on.
