What are some signs a guy likes you buts too shy?

I don't know if my crush likes me he stares and his mouth hangs open I'm too nervous to talk to him but his parents stare at me and so don't his grandma a friend of mine said that he told them I was his girlfriend and his cousin asked how's your girlfriend but I'm not sure what do you think? Please help I've liked him for 3 years I've never felt this way for anyone else but him

FYI I'm person who get nervous easily and I have trust issues which makes things harder for me that's why I'd rather have someone say i like you instead of vice-versa but I'd probably need proof thanks to some people that caused my trust issues
