Why is my ex boyfriend asking me if I’ve moved on or not?

I met my ex after 3 months he kept asking me who I’m seeing, if I kissed my new partner or not , if I have moved on or not, he asked me to show him pic of my current dating partner.
And few weeks ago when v talked on call after ages that time also he kept asking me who I’m dating. Nd when I asked him if he’s seeing someone so he said yes he is but it’s not that serious yet like commitment types.
