Of course this means that you will also be missing your ex like mad, but the whole point of this exercise is to make your ex miss you so badly, that he/she comes back to you. Right now, your ex is probably ignoring you totally after the breakup. Because you won't really know when your ex will be approachable, you want to do something to make your ex come to you.
To make your ex miss you like crazy, you need to do a couple of things. First of all, there must be no contact whatsoever with your ex - directly or indirectly. This means no calls, no messages, no emails, and no talking to your friends about your ex - they will tell him/her everything.
Simply carry on with your own life. You need to heal after the break up as well, so concentrate on yourself for a while. Your ex will heal in his/her own way, in his/her own time. This won't be long though, because you are going to make your ex miss you like crazy.
After a short while, your ex won't be able to take it anymore. He/she hasn't heard from you in a while, and is starting to miss you. Yes, he/she is still a little angry with you, but the love your ex has for you is a lot stronger, and is pulling him/her towards you like a magnet.
There is a good chance that your ex will try to make contact with you. Don't respond though, not yet. Just carry on as you are, doing your own thing and enjoying yourself with your friends and family. One thing is for sure - your friends are keeping your ex updated with everything that you are doing.
Only hearing about you, and not hearing from you at all, is starting to drive your ex nuts. All he/she is hearing is that you are having a ball, and are the life of every party you go to with your friends. Your ex will remember when it was the two of you enjoying yourselves like this, and will want to become part of that again.
The whole situation is starting to make your ex miss you like crazy and your ex is going to make contact with you as soon as possible.
