Are the Y GUYS the JEALOUS TYPE? and do they deny their feelings in fear of rejection?

theres this counselor i work with at camp named Kris who i was cool with and liked and he liked me too(the other counselors knew it 2). but the thing was that my bff doesnt know about the thing we have for each other cuz i didnt tell her yet. so she told me that Kris was trying to get with her and that he's always calling her on her fone, yet at camp, Kris is always flirting with me and gets upset if i dont say anything to him and always hugs me. so my bff tells me that Kris called her, telling her that he thinks shes cool and all and that he has a gf, but its not that serious. later on, she txts him, saying that he's not even a friend to her, so she doesnt know why he's talking like that and she basically dissed him. the next day, he was walking around with some black slut, smiling and acting y. so now i dont talk to him anymore either cuz he just disgusts me with all that foolishness. today, he kept looking at me and my counselor asked him if he liked me and he said no. and she said why?, but i didnt hear his response. and ever since the incident, when he walks past me now, he looks upset and just storms past. do i have right to be mad at him? do u think he's saying that he doesn't like me for the fear of rejection? wat do u think?
