All the questions are going through your head of what you could have done differently and how you can get that second chance.
Before you start coming to conclusions and getting into a certain mindset there are things you should know that will greatly increase your chances and probability of getting her back.
Give Her Some Space.
When your girlfriend/wife decides to leave it's to get away from the situation that is making her upset.
This time is especially important for them so that they have time to think about what they are missing.
If you are constantly text messaging and calling her this is only going to drive her away more.
There is a free video on my website that talks more about the stalking tendencies of an ex.
This is a normal feeling, but being able to control this desire is going to put you at a much better position when it's time to communicate again.
When are you aren't constantly trying to contact her she's going to have time to think about the relationship and hopefully think about how much the relationship meant to her.
After a certain point your chance will arise to make the first contact with her to resolve your issues, but getting past this point is critical.
Be Willing To Meet in the Middle When you girlfriend finally has had time to think about things, and you start talking to each other with a clear head, it's very important to be flexible with your decisions and demands.
More than likely she is going to have things that absolutely must change before she will take you back.
In order to get her back you are going to need to be semi-flexible with her wishes.
Once you are back together you can discuss things further and even get a few things changed that you possibly didn't like about her.
