Knowing the right way to go about how to get your ex back when you know you are to blame for the break up can be tricky. Maybe you cheated on her. Maybe you have been too pushy or demanding. Maybe you have unjustly accused her of things and she just got tired of defending herself. No matter what the reason, you are to blame and you want her back. Though it may seem impossible to change her mind, it can be done if you follow some simple advice.
Before you go running out to beg her forgiveness you should first have a heart to heart with yourself. Ask yourself if you truly want her back. You did do things to drive her away so do you really want her in the first place. Ask yourself if you do get her back will you be able to change the behavior that drove her away. And finally ask yourself if you are man enough to admit to her that you were wrong, take full responsibility for the break up and change your ways? If you answered yes to all of these questions then it is time to take action.
The first rule of trying to reunite with your ex is not to be pushy. This will take some patience and you should give her all the time she needs to come to the conclusion that she does want to give your relationship another chance. During this time of separation, figure out what exactly went wrong. If you cheated on her, figure out why. If you were always accusing her of being unfaithful (when she was doing no such thing), figure out why you were doing that as well. Whatever the problem was, figure out why it became a problem to begin with. You must do this or when you tell her that you take full responsibility you should also be able to explain to her why you did what you did and do it in an honest way. She will be able to tell you are being sincere so do not drop the ball on this part.
Before she can forgive you, you must be ready to forgive yourself and know that even if she does not take you back you are now a better man for having faced your faults. However, if she loves you and only left because she felt she had no other option she will likely come back if you tell her what you have discovered about yourself. If you figured out that the reason you were always so accusatory with her was because you were always afraid she would cheat on you (your parents cheated, your other girlfriends cheated, etc.) then you need to tell her that. Make her understand that you know she did nothing wrong and that your feelings stemmed from deeper issues that you are now facing. By admitting such deep and emotional things about yourself, she will be able to see that you are truly sincere about working out your problems and this is the first step in how to get your ex back in your life for good.
