Last year I was desperately working on how to improve my relationship with my lover.
We had very long distance and had not seen each other in a year.
Finally the relation almost broke up and we started referring each other as "ex".
Then suddenly she realized that there is something that is still binding us; I realized that, too.
Though I was the first one to call but she was waiting for that call literally.
But not everyone is so lucky.
The understanding may not come from both sides.
Your partner could be utterly hopeless and distracted by someone else.
What do we do then?

• We panic, try to talk to her by any means possible, if she doesn't listen go to extreme.
  Some people even try blackmailing.
  
• We start destroying ourselves, or attempt suicide hoping that will catch her attention.
  
• We lose hope and look away just like our partner.
  
• We temporarily change ourselves so that she/he agrees with the new type.
  
• We make promises to keep her/him back, even if we know we can't keep them.
  

Yes, we do all these things.
But do they really help? Temporarily they might get your ex back to you, but when she/he finds out your true self again, or you can't keep a promise you made all is gone.
Remember love can't be won by force.
What to do to get your ex back?

• Don't panic or lose hope.
  Stay calm and try to talk to him/her or write to him/her whatever she/he allows.
  Use your common friends to arrange meetings if the need is to clear up a misunderstandings or ask forgiveness for your faults.
  
• Do not try to catch attention by the wrong means.
  It will only disgust him/her.
  Try to do something good, say social service, make something for him/her, do something you long wanted to do and let him/her know all these.
  
• Don't ever look away.
  Admit your part in the break up.
  One hand cannot clap.
  Let him/her know you are truthful and honest.
  If he/she has faults she/he will try to correct them once she/he knows your honesty.
  
• Don't change yourself temporarily.
  Changes should come from within.
  
• Don't ever make any false promises.
  Be honest and tell.
  That is called responsibility.
