Signs a guy likes you ?

Or is interested in you ?

Also there's this situation with this guy that I started hanging out with after school because he's friends with my friends but we barley talk . Anyways....I have a feeling he might have feelings for me but I'm not sure .... I'm always the first one he says hi to when were in the group( the way he says hi to me is more enthusiastic than to anyone else) and hugged me after like the second/third time I met him , but today he was gonna hug me but stopped and I think it was because the first time he hugged me I didn't hug him back because I was holding my bag and cheer bag but I guess he thinks I don't want him to hug me or anything......

He also always stands REALLY close to me . Like literally two inches away . And I was talking to my other guy friend and he kept looking and then went over there and started talking to him . Do you think he likes me ?
