The relationship ended on a very bad note - you had this major argument that left you both really furious with each other.
The only thing is that you realize that you still love your ex so much and you need to do something quickly to make your ex fall in love with you again.
Be careful though, you might think that you have to rush with this, but if you push your ex too hard, and try to force your ex into getting back together again, it will likely backfire on you and have just the opposite effect.
Your ex will become really tired of your constant calling, and will go out of his/her way to avoid you at all costs.
The only way to make your ex fall in love with you again is to allow your ex time to think about all the great times you had together, and realize what a great person you are as well.
This can only happen if you are not around at all to take your ex's mind off what he/she is thinking about.
At the moment your ex is thinking about you in a really angry way, but I can assure you that this will change as the days go by.
The anger will pass and make way for more positive feelings towards you.
The argument you had will seem a really stupid reason for ending the relationship, and your ex will start to have second thoughts.
Slowly but surely memories of all the good time you had together will become more frequent.
He/she will start to think a lot more about you as well.
Not seeing you at all will make these feelings become stronger and stronger, until it becomes so bad that your ex can't take it anymore.
The second thoughts that your ex is having about you will lean more towards the positive side and eventually make your ex fall in love with you again.
