Your boyfriend will be begging you to give him a second chance once he sees or you make him believe that no other women can love him the way you do. Here are a few ways to get under his skin.
Ignore him for a while
This is an old tactic, but it works pretty well. If you ignore your ex boyfriend he will assume you have found someone else. When people break up they often want the other person to hurt for a while, or they want to be the first person to move on. Don't give your ex boyfriend the satisfaction of seeing you sulk or cry over him.
You'll only boost his ego and make him believe he must be really something if he was able to have this kind of effect on you. Ignore him completely, don't try to beg him for a reason why he broke up with you or try to convince him why he should want to be with you in the first place. Ignore him and you'll attract his attention.
Flirt with other guys
You can wait until he comes around and then flirt with other guys in front of him. This will let him know that you are moving on with your life and not spending time thinking about why he dumped you. Your ex may want you to believe that you'll never find a man like him again, or that you are not desirable to other men. Let him know otherwise by letting him see other guys beg for your attention.
If he sees that other people want you he may get the sense that he is missing out on something. The more value other guys put into you or the more you can make yourself desirable to other guys the more he'll want you back if not just to keep you from the other guys.
Put your best foot forward with other people
Put your best foot forward with other people you meet. Here is what I mean - you want your ex to see you making it easier for other guys to get along with you than what you may have made it for him.
Don't get me wrong; I don't mean that you should be promiscuous, I just mean giving him the illusion that you are. To add a little insult to injury, try to do it with guys whom you think he believes he is superior to. If the cool hip guy has to jump through a million hoops to get with you, and the nerdy guy seemingly gets you with no trouble at all this will drive him nuts.
These tips may seem silly, but trust me they do work if you take them seriously.
