easy. You tend to go back to the same person long after you have broken up. It is very important to be honest to yourself about the situation and then only you would be able to understand what actually went wrong in your relationship.
The first thing you can do is to try to talk about the problem to your ex. Pursue him or her but do not be too pushy. You should be sensible enough to see if things have not gone way too far beyond correction.
Make him or her realize that you really want this to work and that you are ready to that extra mile so that they can be together again. Make your ex feel good and try to win the trust back. Be honest to yourself all the time.
Always remember you have to rekindle the love that you people shared. Do not fight over things which are trivial and try to chalk things out between you and your ex as if once you know the problem, it is easier to fix them up.
You should be flexible to the circumstances around you. Being too rigid would not get your ex back into your life. Be yourself and act as you feel. You need to be comfortable with your own emotions and then only you would be able to talk to your ex about the problems.
Never try and convey your state of being to her through people to gain sympathy as this will make you look like a jerk in front of others. Though relationships have a very strong emotional base, you actually need to take a lot of care while dealing with things.
