Is my Ex trying to make me jealous?

Kobekipara
why would an ex (dumper) try everything to make you jealous even when you do not react? More especially one who was never active on social media but suddenly feels the urge to.
P. S:I neither resisted the breakup nor begged for him to stay. Any insights please... thanks.

Was a Long Distance Breakup. He insisted on being friends which I respectfully declined stating that I would need time for that to play out for me and that he should be able to understand and respect my decision as I did his.
