You're broken hearted and desperate.
But do you know that all is not lost..
..
even if your ex can't stand the sight of you - they loved you once..
..
and I believe that they can love you again.
#1- You've Said Things You Wish You Could Take Back It's probably true that when you and your ex broke up that you told everyone you knew awful things about them that you didn't really mean.
  You need to clear the air with your friends and loved ones and let them know your intentions of getting back together.
  Explain to them that you didn't really mean the awful things that you said, they were the heat of the moment, and that you need their support to win back their love.
#2 - Be Realistic Why do you want to get back together?  Is it because you hate being alone or because you REALLY love them?  You need to be honest with yourself.
  If there were good reasons for you ending a relationship those reasons are still valid.
  However, if things got out of hand and you broke up for the wrong reasons then you need to do what it takes to make things right.
#3 - Are They Still Available? Of course the best time to get back together is as quickly as possible after a breakup but that's not always possible.
  If they're single your chances are still very high.
  However, if they've moved onto someone else then you need to tread really carefully.
  What works in one situation won't work so well in another.
#4 - The Reasons Why You Broke Up Are Still There They're still out there, like they say in the X Files.
  If you can't talk about what led to the breakup then you're really not ready to try and fix things.
  Be prepared to hear some hard things that you may not like but your ex will respect you for listening.
