Right now, there is no way that you will be able to make your ex yearn for you.
He/she is absolutely furious with you, and doesn't even want to see you, let alone speak to you.
This is understandable, seeing that the argument you had was so messy, and you were really nasty to each other.
One thing is for sure though your ex won't feel this way for very long.
As soon as he/she has had enough time to get over the break up, the realization that he/she still loves you will set in.
Then your ex's whole attitude will change - from bitter resentment, to that deep love that he/she felt before the break up.
Although it must be really encouraging for you to hear this, don't rush into anything just yet.
No one knows how long it will take for your ex to feel better after the break up - everyone is different.
So just carry on with your own life for now - what you do will eventually make your ex yearn for you.
Obviously your friends know that you and your ex have broken up, so use this to your advantage, and get them to help you make your ex yearn for you again.
You don't have to do anything specific, simply go out and have fun with them - as much as possible.
They are the link between you and your ex - they will keep your ex informed as to what you are doing all the time.
So, the better behaved you are, and the greater you look, you can be sure that your ex will get to hear about it.
There is no doubt that while you are out with your friends, other guys/girls will become attracted to you and hit on you.
It's actually important that other people become interested in you - your ex needs to realize what a catch you are, and what a big mistake he/she made in breaking up with you.
As soon as your ex hears how popular you've become, this will make your ex yearn for you again.
So don't sit around waiting for your ex - go out and enjoy life to the full.
You won't even have to make contact with your ex.
He/she will get to hear all about you from your friends anyway.
After just a little while you and your friends are going to make your ex yearn for you, and your ex will probably make contact with you.
