Guy's Behavior

Would you consider these to be signs of hidden jealousy?

There's a guy I feel he likes me, but he's not very clear about it and started feeling signs that he might be jealous (not sure though). So once for example I told him there was another guy trying to have a meeting with me, and he started asking me if I finally went to the date. And when I said I didn't he said, well, he should have been me (because we had meetings). Or, another example, I told him I was going to have a photoshoot with a guy I met, and he started saying things like "of course, go and show him your intimate areas", and then saying that I shouldn't be meeting people when I was sick (I had some fever at those times). So even though it sounds rude (in general he's not rude) I started thinking if his reactions were a sign of jealousy or what. What do you think?
