If you are more than certain that you and your ex definitely had something special and you are sure that your Ex will always hold something special in their memories for you, then there is actually a very easy trick to get them to come back to you, if you still want them.
This is the very undesirable yet effective, "No Contact" rule.
Why it works so well is very simple, because no contact means more mystery.
If you both had shared an intense relationship then the best thing to do is to keep away and respect the No contact rule as it will always keep your ex guessing about your life.
If they had spent a considerable amount of time knowing the details of your life and what you are doing, then this no contacts rule will make them desperate to know what you have been up to.
It will always work in your favor to leave those details to his or her imagination.
However along with surrounding yourself with mystery and formality, you must also make sure that your mutual friends talk about you in front of your ex.
This will ensure that your ex still thinks about you and only hears snippets about your life from them but never the full story.
Finally the day that you do call, after a considerable amount of time has passed, your ex will be too pent up with frustration and curiosity to know how you have been doing and there is sure to be that connection struck again.
