If you want your ex-boyfriend to be jealous you have to flirt with someone he knows right in front of him. To make your ex-boyfriend to want you back is start being more sexual and also flirt with him a lot of times.
You probably can, but why would you do that? If you do it, you will gain a reputation that you do not want.
tell him you want him back!
I don't know, but if you have already told her and she hasn't talked about it back I probably wouldn't chase her. P.S. I have the same problem
usually; you always want what you can't have
Honestly, if ur a good boyfriend. and you honestly know it and knows that she really likes you too, then ALWAYS is my answer.
You tell him that you love him more, and wirte him a note and give it too him at school , telling him that the other girl is just playing him, and you love him and you want to back more.
get another boyfriend and make ur ex boyfriend jelous
why did it ended in the first place?
Whip your hair back and forth
By just kissing him. Then he knows that you wanted to kiss him
He says, "I want you back."
