What seems logical and feels natural is not always the best thing to do, especially not when we are talking about relationships.
  So, how do you get your ex girlfriend back in to your arms? First of all, know what you should not do:

• Do not beg
• Do not tell her you miss her and that you cannot live without her
• Do not act depressed to make her feel sorry for you
• Do not bring her gifts and flowers to get her to know that you love her
• She already knows that.
  She realizes that you love her and are will do almost everything to get back with her.
  Of course she does.
  A woman knows these sorts of things instinctively.
  

Instead, what you must do, is to act like you really do not care.
You can get whatever woman you want and if she is acting up, well, you just go find another.
That is the attitude you must get.
Never ever show signs of depression or that your life is worthless without her, it will only make things worse.
You see, a woman wants a man who is emotionally stabile and can take care of himself.
She does not want a man who's life is only worth living when she is around.
It is much more fun to be a part of a real man's life than be the leader in yours.
So go ahead, live life and show her that you can do perfectly fine without her.
Then she will be one that comes crawling back to you.
However, realize that while you are growing from being a boy to become a real man, she is out there, being approached by 20-50 men each and every day.
So, do not wait for too long.
