I want to make my ex boyfriend jealous how can I some one help me?

Here's a suggestion: forget about the whole thing.

I know it's hard and it's fun to make people jealous. I realize you're younger than I am, but I was in that position just a few years ago. Playing games like those makes you very immature and very, very high school. Take it from a college girl and just move on! You're going to have to kiss ALOT of frogs before finding Prince Charming, so get a move on and forget about him! In the end you won't feel satisfied about making him jealous anyway.

My friend wanted to make her ex jelouse and every1 kindda realized what she was up to and that was not a good resault, Because after that her ex started making fun of her. Plus when a girl tries to amke her ex jelouse people think that she is jelouse herself so she is trying to make her ex feel the sme way, And to be honest it's not a good impression to make. I highly recommend you let Karma pay him back.
