You are not alone.
Many people are or have been in the same position as you.
Most of us go through the trauma of a broken relationship sometime in our lives, and many of us have no clue what to do when faced with the stark reality 'how can I get back with my ex?'.
And because it has happened to most of us, there are proven methods to get your ex back that will help you.
The circumstances of your breakup will obviously dictate your best course of action, but generally the first thing you absolutely must do is consider your girlfriend a no-go area.
Leave her alone.
She too will have a tsunami of thoughts and feelings in her head that she needs to resolve.
A constant barrage of calls, messages and such will not give her the peace and thinking time she requires.
And while you are doing this, you are not doing any rational thinking yourself.
Step back.
If there is any chance of reconciliation between you, your ex needs the time to reflect on the good things between you...
and only then can she start to miss you.
And this is good.
Get on with your life, and although we know it is never the same life without her, you have got to get out and 'do stuff'.
You must have some distractions in your daily program that will prevent you from churning over thoughts of your ex, and making sudden and impetuous decisions to react.
Be aware above all that when the time is right to make contact with her again, this is a time for clear, honest communications.
Any attempts at psychological games will not work and will almost certainly backfire on you.
Be sincere, be sensitive to your ex's own feelings, and demonstrate the characteristics that she found so appealing in the first place.
Mending a broken relationship does not have to be difficult
