Women are fickle creatures, one moment they love you and then hate you the next. You may feel that you have not made any mistakes, and perhaps you do. Or you may be well aware that you have turned everything upside down. In any case, she can finally decide to forgive you, based on the seriousness of your behavior.
Steps
Step 1. Don't imply that you haven't made a mistake
If you really want her to forgive you, don't act like you've done nothing wrong. Show that you understand what you did and it won't happen again.
Step 2. If you haven't already, ask for forgiveness
Don't just say sorry. Express your repentance in an intellectual way and avoid acting silly, otherwise your feelings will not appear sincere.
Step 3. Give him a semblance of sincerity
No, it must be sincerity! Your request for forgiveness must seem credible. If you don't show that you believe in yourself, she surely won't believe what you have to say.
Step 4. Show how sorry you really are
If words don't solve your problem, you need to be able to earn your forgiveness by doing something you normally would never do. Make sure she understands the efforts you are making and that she knows she really matters to you.
Step 5. If words and actions don't lead to the forgiveness you desire, time will
Perhaps it may take some time to reflect on what you have done. Finally he will collect his thoughts and make his decision. If you've really done it hard, time may be the only solution. Perhaps he will end up accepting that you screwed it up, but then learn from your mistakes. Sometimes however, there will be no going back, and although she may choose to forgive you, things will never be the same again.
