If you want to win your ex back, then you must do something to change your ex's thoughts and feelings towards you.
How, I hear you ask? Now that they have left you, there is maybe no way to communicate with your ex to make his or her mind change.
It sure sounds like there is no hope - but there is.
Here is how I won my ex back after a breakup - (and everything seemed so hopeless!) applying very powerful mind tricks.
Now, of course don't expect some "Star Wars Jedi Knight" type "force" or something - the reason these are called mind tricks is not that they are magical - it is that they are extremely powerful in changing your ex's mind about you rapidly.
When my girlfriend left me and after doing things I could think of to win her back; I thought there was no hope.
But no - I was taught the powerful psychological methods and now I am going to pass them onto you.
The key on how to win your ex back is to turn the tables on your ex.
I will explain: People want what they can't have, right? This is the most fundamental of psychological principles.
At the moment this principle works to your disadvantage.
Your ex knows that you are easy for them to get (since they know you want them back!) so this work against you as their subconscious tells them to keep away from you since you are easy.
If you want to win your ex back, the ultimate way to do so is to turn the tables on your ex and make them think that you are not so easy to get after all - you have moved on and are doing just fine.
This works so unbelievably well (and fast) if done correctly, that it is rightfully called a mind trick.
