No matter what has led to the breakup with your partner, you can make them miss you.
Either you are at fault or it is your ex that is at fault you can sure make them miss you so badly that they will like to come back for you.
"How can I achieve this?" you can achieve it and very easily too.
The only way you can make someone miss you is for you to make yourself scarce to them.
Don't call your ex for any reason.
Not calling will surely make you gain back some of your respect and dignity from your ex.
When your ex doesn't hear your call, he/she will find him/herself waiting for your call, because they have seen it as part of their daily lives.
They will be plagued with the thought that you are probably seeing someone else already.
This can even make them feel lonely.
As time goes on your ex will find themselves remembering those good times both of you have shared together in life.
Naturally they will desire to have a repeat of those past good times.
But alas you will not be there to give it to them, so they will seek to get you back.
For the time being you need to tush yourself up, get to live life, you have time on your hand live it to its fullness.
Make life interesting for yourself, give yourself a 'facelift' move around with friends, and always wear a smile.
For sure, one way or the other your ex will get wind of how you are now enjoying your independence and they will come seeking you out because they have been hungry for you all these while.
They would have missed you so much that they will want both of you to get back again for a restart.
