While you really wish to get your ex girlfriend back, she is ignoring you completely! She doe not answer to any your text messages, emails or calls. I have a lot of things to say to her, her attitude makes you disturbed so how can you if she just won't talk to you?
Your ex is ignoring you for a reason. There are probably also things that she would like to say to you as well, but she knows that if you two get together right now, there'll be another huge explosion. This is because you are both still too emotional after your break up, and your ex knows that it is not the right time to get together yet. She wants to take some time to think things over first. This is very clever.
Now to get your ex girlfriend back, respect her wishes to not talk to you right now, and do the same thing - leave her alone, and DON'T contact her. Don't let it bother you that she is giving you the cold shoulder now - use it to your advantage. Take some time to heal yourself as well - there is still a lot of pent-up anger inside you, so just relax - there is plenty of time for you and your ex to get together and have a talk.
As you know, anything you say to your friends about your ex will go straight back to her, so make sure to say really nice things about her. This way, you're using your friends to make contact with your ex for you. What she hears from your friends will probably soften her attitude towards you, and she'll start missing you.
Sooner or later she'll get the feeling that she would really like to talk to you again.
