There is a girl I've been friends with for about 2 years now (HB8-9). Last year, I had total one-itis for her for 10 months. At that point in my life, I was a total beta, had no sense of game, etc. Now (I'd say about 2 months into swallowing TRP), I see that I spent those 10 months drying up her pussy to no end by being a nice guy. Even if I wanted to fuck her, there is no recovering from those 10 months, and there is nothing I can say or do to make her forget that version of me. She's like a sunken ship. I recognize this, and have elected to stunt any attraction toward her. We still hangout, go to the same parties, have mutual friends.

Question Nowadays I practice TRP's methods on her. For example talking in a low, controlled tone of voice, not being responsive frequently over text, paying attention to other girls instead of her. Now she frequently asks, "Do you hate me?" and then goes off on a tangent about reasons why she thinks I hate her. I respond with a calm and collected no, but more often than not with a more witty/sarcastic response. In this aspect I sort of have her in the palm of my hand, and I believe keeping her on her toes about whether or not I can tolerate her is a good thing.

Is practicing TRP on her a good thing to do? I am fairly new to the game, so practicing on a safe bet girl that I do not have intentions with makes logical sense to me. Any advice helps.

Sidenote: I understand that practicing on a more "consequence free" or "throwaway" girl may prove to be detrimental when I am actually out in the field. I believe it is a good thing to do considering how new I am to game.
