If my ex boyfriend has a new girlfriend now, why does he still feel the need to find out whether I'm over him or not?

He jumped right into a new relationship with some random girl he just met when we broke up. Now he's trying his best to get my attention and he's rubbing this new relationship to my face and see my reaction. What the heck?
He's trying to get an ego boost or feel he won the break up
He's moved on but doesn't want you to move on
He's trying to figure out if you're over him so you two can be friends
He knows he screw up and he's trying to make you jealous so that you'd go after him and he gets out of begging you back
He's still into you and he wants to know if he's still got a chance
He wants to keep you as a backup plan
He's hurt and wants you to hurt too
