Will a guy get jealous and possessive over a girl he's not interested in?

Anonymous
My guy friend claims he's not attracted to me, doesn't want to get into anything with me but gets upset whenever I hang out with my other male friends; as in whenever I'm talking or joking with one and he notices, he'll literally walk over and interrupt our conversation. He will also make rude comments if he ever overhears me talking about another guy with one of my girlfriends and whenever we go out, constantly keeps his eyes on me when he thinks I don't notice.

So just curious, is he interested or just maintaining "ownership" because he knows I liked him at some point? I know he's had a really bad relationship just two years ago and he once told me he's scared of ever falling in love again- don't know if that has to do with anything though. Opinions?
