Guy's Behavior

Advice on guys?

I need some advice with my college life. Before half term, there's this guy John. He was the one who made me confident in class. He always sat with me and we’d gossip together. Then after Christmas break, I came into college with a new makeup look. I sat at the back, John comes in late and he sits at the front. He turns round and sees me. And he's in shock. And he said he likes the new look and to keep it. And then this other guy, Sam. Sam came in late. And he looked at me and said I look different but in a good way. And he was checking me out

That same week John kept on asking me why I changed my look. He showed Sam a picture of me before half term and said 'doesn't she look different?' Sam said 'yea even the makeup look.' I found that very odd since guys don't even know when girls are wearing mascara. And I found out that Sam told 3 girls in my class that I'm the prettiest. John also said I'm a perfect picture.


However after 2 weeks into the new term. John has switched up with me and he's just rude towards me. Doesn't sit next to me. And he doesn't like when I'm around and he tells me to go. And now he's always talking to 2 of my friends instead of me. And I'm not sure why since i haven't done anything wrong/said anything to upset him. Once I came in late and John said 'what happened today you look uglier than usual.' I just ignored him.

john knew I liked this guy in our class. And he helped me talk to my crush. But one day he pulled prank on me and his friends were in on it too. He told me my crush is leaving the college. I started crying. He only told me it was a prank later on in the day. He then sat next to me next lesson, and asked if I was mad at him. He got into a physical fight with a guy in our class. And when I walked in he told me to protect him. So I broke the fight up, and asked them what had happened.

Does john just suddenly hate me or is it something else? Please help me I cannot figure this out

Also I feel like Sam is trying to move to me but subtlety? I’m not sure. He’s already established that he finds me the most attractive in my class. And around 2 weeks ago, he was like to me ‘how are you? We haven’t spoken in a while. why do you look so depressed?’. Then earlier this week he randomly said ‘I’m a big fan of you.’ And I have no idea what that implies. And there’s a video of me that my friend took, and you can clearly see him checking me out.

And with John. I was talking to another guy in my class. And John gave me a weird look. I don’t know what the look was I think it was kind of a jealous look, but as if he was trying to hide it. Then he threw a pen at me to get my attention and when I looked at him, he gave me a pissed off look. He also made a joke that I gave him head. And earlier this week I came late to college. And when I walked in, he gave me his laptop straight away.
