I like this idea. I will give this a go soon. I doubt it will work because I think this girl has almost no interest in me anymore, but it's probably the best thing to do. Thanks for your help.Don't send that message. It looks like you're trying to guilt her into actually making contact with you. I think it would be better if you sent a message along these lines:
"Hey, I've been doing some thinking, and I would have to say that I am really not grooving on this at all. So I think it would be best if we were just friends"
This message is the ultimate "what the fark?" on her part. Women are not used to getting messages like this, and she will be extremely confused on what you mean and why you say it. She will attempt to contact you to figure out what is going on. Do not respond and give her the cold shoulder for at least 24 hours. Then you can respond with something that asserts yourself in higher standing. Don't explain yourself though. You don't need to explain anything, it's her that needs to do it.
If this is not the case, then oh well. You asserted yourself and left her in a higher standing than the other way. In other words, either way you win.
Just because you have had a few bumps in the road does not mean you should quit. By continuing to obsess over your desire for success, you will only impede yourself and bring about more suffering. The key to feeling great is to eliminate your desires and just let things happen. Since I've started doing this, I have been successful with three different women in TWO DAYS! Take the energy you funnel into your desires and put it into taking the necessary paths to conquer it.
