At the end of a relationship it is not uncommon for one of the two individuals involved to want to reestablish the relationship, if you are the individual in question working smarter not harder is the best plan of attack.
This is what some might call an underhanded tactic, but it does work as long as the other party does not realize the game you are playing.
Depending on the nature of the break up the individual who has decided seeing other people would be best might not be truly ready to let go completely.
If this is the case then your chances of using stealth and cunning to win them back are enormous if you play the game correctly.
Since you are trying to push someone into something without them realizing it, you are in effect playing mind games, and you need to be sure that it does not blow up in your face.
The first thing to do is non-communication.
Do not get in contact with your ex for at least two weeks.
While you are not communicating go out and have some fun.
Make sure your friends see that and believe that you are enjoying being single.
If you have some mutual friends this will get back to your ex, and they will believe that you are doing better than they are, and they will feel like they are missing out on the fun.
Once communication is reestablished let your ex know that you are doing well without going into detail.
This will have the effect of making your ex think that your life is more put together than theirs, and they need to organize their life.
This is preparing your ex to reestablish a relationship on your terms not theirs.
This is a delicate game that you are playing so discretion is the key.
You want to first establish the "friend" role.
This is the most important step in the game, and can take the longest amount of time so do not rush.
When your ex wants to talk just listen, they will find this new and refreshing and will start needing you as a confidant once again.
Once this part of the relationship has been established it is almost the time reestablish the relationship.
Let your ex chase you, instead of the other way around.
Do not reveal that you want them back, but let them make the first move.
While this type of tactic does work, it is important that your ex does not figure out what you are doing.
If they do they could turn the tables on you, and it might have disastrous results.
Play your cards close to the vest, and let think that they made the first move.
Remember that all is fair in love and war, so play this game for keeps!
