What is he doing to me?

I really like this guy. We spend a lot of time together as he is a lodger in my parents house. We make each other laugh and he always acts goofy and flirty with me. However he recently went on a date and my world crumbled. I tried to act mature about it and asked him how it went and he said well. When I asked him if he was going to see her again he raised his shoulders and said nothing. Then a couple of days ago when he was asked about “his girlfriend “ at the dinner table he said he did not have a girlfriend and I noticed he looked at me when he said that. But he has been acting a bit differently lately. I don’t think he has seen her again though it has only been a week. I also don’t know where this girl is coming from as he is always soccer training and then home and never goes out. I have a feeling one of his friends may have something to do with it. I know I can ask him myself but whenever I do he likes to wind me up with answers like maybe o r he says he does not have one. Does he have any feelings for me at all?
