Can a f37 and m37 live together and do everything together and still not be together?

F (37) and M (37) live together for 3 months

So I live with my best friend and we do everything together. But yet he says we will never be in relationship or anything but yet I go to all of his family things and he goes to all of my family things. We take road trips together and he gets upset if I am not out in the living room with him. We eat super together every night. And when he comes for lunch when he is working and I am off he is wanting me home so he can see me. He went last Wednesday night for trivia to say hi and sit next to me and then left. Made it a point that he was going to see me at home. I guess I am asking what does this mean should I stay or should I find a another guy?
