He says that we are friends with benefits but he acts like my boyfriend?

So I've been meeting up with this guy and we have been sleeping together but we also went for something to eat together and on a walk. We are only sleeping together but we get along great, open up to eachother, text everyday and are always around eachother in work. But he keeps asking me every night if I'm going out and if I've been with any guys. He asks me where I went on my days off and he checks my phone and reads through all my messages. He even saw messages from me and a good male friend of mine and we were sending hearts and telling eachother that we miss eachother and he wasn't happy that i didn't tell him about this male friend of mine and he looked really upset. He also start asking if I ever kissed this male friend and he was disappointed because I was friends with this particular guy and he was saying that I could "do better".

He also holds my hand when we are together and kisses me before he leaves me. He also always asks me if i missed him and he said that he missed me too. He also said if I got a boyfriend that he would be jealous. Is he my boyfriend but labelling it as friends with benefits since he's too afraid to commit? Does he have feelings?/
