Why would an ex try to make you jealous?

[Anonymous]

Flaunt a new girl around you etc.

It could be he’s just moved on. I only say this because my ex accused me of this recently. We go to the same college, and I’m seeing another girl now. Inevitably, our paths crossed, and my ex accused me of just being with the girl to make her jealous. That made me really upset, because I’ve just moved on, and I really like the girl I’m seeing now. She tried to invalidate all of my genuine feelings. So be careful about coming to this conclusion. However, if you truly believe he is trying to make you jealous, it’s because he’s immature and wants to get back at you. He wants to “win” the breakup. If this is the case, he’s not even worth your anger or expense of emotions. You deserve better.

Because they want you to regret breaking up and want to show you that they can find someone else and don't care about you. It's a typical case of them hurting inside and therefore they're going to try and make you feel like crap also. + They enjoy having your attention and want you to be thinking about them.

Because some part of him still has feelings for you.

to make you feel bad and like you've lost out, its a petty tactic but guys seem to think this works

[Kindredspirit1]

does it mean the guy still likes his ex?
