Ok,

So One-itis is a problem for many people out there. And for me too. The reason for getting One-itis is obvious, you lose a chance, you lower your potential value by letting go. You push it so hard that you scare the girl away and do not stop until it is too late. Hollywoods fault, work hard enough and she will be impressed... Do not think like this.
The big secret is that most people cling to hope for far too long. It is difficult to fight something that you do not want to fight. You are playing yourself (playing both sides but cheating in the other sides favour). In order to get rid of this, the first thing you need to realize is that you do not really want to get rid of it. It feels good to be in love "in love". You still feel that it is a temporal setback and tomorrow everything will be back to normal or better.
Your friends keep telling you, forget her, shes bad for you etc etc. You keep saying: yeah, I know, shes bad.
Secretly you think, but shes not like that, shes a good girl, I dont wanna forget her, just need a few more dates and... There is still a chance.

Guess what, you do not try to get rid of the One-itis, you protect it. You do not want to move on, change is scary.
I recently understood this, I needed to let go of something I have desired for a long time (and had for a long time). Only now I have understood and gained perspective. All the advice you get from others make sense AFTER you have decided to let go. From there you can see it clearly, from this point the sky is the limit. But you have to accept the fact that you actually let go.
