Would you say he’s jealous?

I speak to this guy and I’m not sure what we are. I posted something about a date and he was acting weird by ignoring me and stuff. Asked him if he’s annoyed he said “nah.” I then said it’s not even a big deal and I’ve cancelled it. He then replied “ok if it’s not a big deal enjoy?” Would u say he’s jealous?
