Break off all communication with your ex and leave her alone. She has dumped you for a reason and if you want to win ex girlfriend back, then ignoring her wishes will only send her in the opposite direction. So accept that by leaving you she has expressly and physically demonstrated her need for some time and space on her own and honor that.
Instead, spend the time away from her thinking about what went wrong and what was your role in the breakup. If you made a mistake that caused the breakup, don't waste time beating yourself up and feeling sorry for yourself. Instead take a long hard look at your behavior and take the necessary steps to change whatever needs changing.
Do you have anger issues? If you do then you should seriously consider talking to a professional who can help you cope with this and find different ways of expressing anger that do not threaten or cause harm.

Did you find yourself cheating on her even though you loved her? Well then take the time to find out why you were doing that and what you can do to stop temptation when it next comes along.
The truth is whatever the reason she walked out on you, to win ex girlfriend back you're going to have to do some serious and some honest and sincere work. If she has gone as far as walking out, then a flimsy gesture to get her back won't work. Believe her actions: she is ready to put your relationship on the line if things don't change.
