Mucho nice to majorly mean?

me and this guy met around 5 years back at camp. He randomly introduced himself to me, and we became really close really quick. we told each other everything, and he told me that i talked to him the way he talked to another guy at my age (3 years difference). One night he randomly called me to church, and when i went there he was waiting for me with his arms folded.when i went to him, he quickly said he had to go. he imed me saying he was afraid of getting too close, because he felt he was going to hurt me. He never talked to me again.he never picked up the phone,imed,anything.. He makes it obvious that he is ignoring me at church.. He seems really heartless now. I mean from the sweetest guy to the biggest *****. Now whenever he sees me and he’s with s someone, he laughs at me, talking loads of crap. Some people say that he’s a closeted gay, and is afraid to come out. I see him looking at me sometimes. I don’t know why he totally ignores me now. Never got an explanation. Tried asking but he ignores me. What is your guess?
