How can you get your ex girlfriends attention?

Many people will be giving you advice and tricks that will allegedly help you get your ex girlfriend back. But none of them, I think, would really work if you really don't know exactly what you are trying to do. To get an ex girlfriend back to and have a new relationship with you again, you must give her a very good reason to get back. It is not something that is tangible that you should offer just so she will be enticed, but something that she should understand that getting back to you is the best decision to make.
