Search Results: getting upset at a guy

I like this guy. He does Zoom quizzes online and we talk all the time. We have been in touch with each other for four months now. We talk pretty much every day since then and we talk and see each other on camera a lot. There is an American girl called Nicole who he has never met who he recently told me told him that she is single. He told me recently as well that he doesn't want to be in a relationship or get to know anyone. He knows I am jealous because I asked him things like does he fancy her etc and he told me, "Sorry but don't want you getting upset for talking to someone else that's just silly". We were on camera again last night and this girl Nicole was on too. We were doing a pictionary type of game where people draw and everyone has to type what they think the drawing is of. After a while, I lay back away from my laptop while still on camera and looked at my phone constantly smiling. Next thing he said was, "Me and Nicole said that at exactly the same time again. Me and Nicole are so insync. Me and Nicole are so innnnsssyyynnnccc". I then looked at him on my screen and he looked to the side which I'm guessing he was looking at me. I then looked back at my phone and I continued to constantly smile again even though I was jealous. I didn't want him to think it made me jealous.

Why did he behave like this with me last night? Does he fancy me? Is he trying to make me jealous?
