Leave your ex-lover alone and give her space for a few weeks after you break up. As you cut off communication you will find that this is hard for you but it will also be hard for her. Your tempers will have time to lessen without communication especially if she or you were angry right when you broke up. By leaving her alone she will have time to think and remember the good times you two had. You will also show her how independent you are on your own (getting back together with an ex). You should also not hound her friends and family for help and advice. By calling her closest friends you will embarrass and anger her and may ruin any chance of reconciliation. By giving her space and time alone she will be able to miss you and feel her sadness without you in her life. This does not mean that you should be distant or ignore her if she contacts you. You were both individuals when you met each other and you by allowing her space it will show that you really care.
