Make him/ her jealous.
That means that he wants you back but you get a guy and make him jealous
Say that you are sorry for what you did but if they don't come back, then follow him around with someone else and try to make him jealous.
He might be trying to make you jealous, but he may also just want his ex- girlfriend back. In this case, usually your ex- boyfriend can try to make you jealous which can mean he wants you back and by making you jealous you will come back to him, or it can also mean he is trying to show you how much you need him, but you can't have him. The real answer is, no body can know other the the ex- boyfriend himself.
if he doesn't like you then he won't get jealous.
Make him jealous:)
* Don't waste your energy trying to make your ex jealous. Move forward and get out with friends and have fun and start dating again. There is a small chance that if your ex sees you with another he will get jealous and come back into your life, but it's a small chance.
