It really hurts when you come to know after a long solid relationship with your partner that he/she has been cheating on you and now is leaving you.
You definitely want to win back your partner but at the current time you are chaos and your emotions are mixed and scattered.
To get back the ex partner you need to be careful enough and think a lot before you do anything.
This is important for repairing the broken relationship.
The first thing to be done is looking into the matter and identifying what made the situation occur.
The cause of this major step by your partner if identified can help you a lot in your future planning.
If you both had an argument and you were at fault, it's better to leave him/her alone for some time.
This will give the ex a chance to realize his/her mistake or heel the hurt feelings.
Once done with that, he/she will start missing you.
This distance from you would be blessing in disguise as it will make him/her to come near you.
But if the fault is yours and you made the split occur, you better be sorry for it and apologize to your ex partner.
Tell you're ex partner that you are sorry for the causing the pain and you really understand how it feels when one gets hurt.
Confess your fault and leave the rest to your partner to think about.
Don't try to contact your ex immediately and start talking about rebuilding the relationship.
Time is required for getting the hurt feelings pass.
Once so, your ex will be ready to talk to you.
This is where you should not miss the opportunity of winning the ex back.
To bear with the pain and the diverse emotions you both are going through, both you and your ex need time.
Be friendly, warm and light to allow the development take place right from the first meet after the split.
Be gradual! Don't hurry because you need to win back the ex partner.
Your patience and understanding will help you a lot more in the relationship rebuilding than a hurry act.
