Your scenario may be something like this.  You had your boyfriend but now the two of you have broken up and another woman has him now, a woman that practically stole him from you.  Now, for that reason you want to win the ex boyfriend back.  If you think that the two of you should be together and not him and her than you are in the right frame of mind to get him back, but how?  Play it with dignity and be smart about it and you will succeed.

Your ex boyfriend's new woman may get nasty if she is trying to keep him from you.  You should not get nasty back because that will do nothing but make you look immature and also cause a feud between you, her and your ex.  You will want, instead, to show your ex boyfriend that you are more mature than the new girlfriend and more like a real woman than she is.

You need to gain control of your own emotions and suppress any instinct to fight.  You are too good for that so be mature and don’t act that way.  Your boyfriend will soon realize that obviously you are a more mature woman than his new girlfriend.  Use positive thinking to conquer the situation, Resort to saying nice things instead of angry things.  To win the ex boyfriend back you need to make it clear that you are the better choice for him.

You may have noticed that she treats him poorly.  Try talking to his friends about this to see if they agree.  If his new girlfriend continues to treat him poorly you may have to intervene.  Get together with his friends to see if they have any idea how you may be able to help.  Having his friends working with you will make it much easier to win the ex boyfriend back.  Using his friends in a positive way will be one of the better ways to win any ex boyfriend back.

Your ex boyfriend may seem like he is under a love spell with the new girlfriend.  You'll need to find out what it is that she has on him and try to think of ways to show him he deserves better.  She may have him overly obsessed.  His friends may be able to help in this situation as well.  If his new girlfriend has such a hold on him that he never sees them anymore, they may very well want him back also. If you are on their side they will be more willing to help.

What you need to do is convince as many of the ex's friends and family as you can that he is better off with you than with the new girlfriend.  All this effort will help to win your ex boyfriend back.  You want so many people against his new relationship that he suddenly sees the light.  Don't directly involve yourself in him and his new woman, but let others indirectly do the work for you.  You should work behind the scenes.  If the other girl catches on to what is happening she can’t blame you all that much.

To get what you want, which is to win the ex boyfriend back, you need as many people on your side as you can muster. You don't have to be the only person fighting your ex boyfriend's new relationship.  In fact, you shouldn't be.  You want him and her to feel it is them against the world so that the relationship crumbles under pressure.  It may not always work but usually it does.  Then you will be able to step in and win him back.
