Hi! sorry I cried! pls unblock me!:)

I know I haven't been on here for a while, and I'm sorry about that. I just couldn't think of anything to write. But, now i need peoples opinions on something that happened recently because i am not doing so good..So, Theres this guy (big shocker for my blogs), we'll call him Andre. I've been wanting to be his friend for a while because he seemed sad. I'd see him in my classes and passing by in the halls with no one to talk to. I just couldn't decide if he wanted someone to talk to or to be left alone. I made some small talk with him, but nothing really significant. Until i needed help on a research project i was doing. I decided to ask him, and he agreed! So, i got his number and we talked the rest of class abotu music and anything random i could think of. He even mentioned he'd noticed me before when i hadn't appeared due to sickness. I thought everything was going good after he asked for my insta. till now. After texts about the project and questions about himself evetually he just stopped responding. I assumed he'd been busy or gotten sick (given him not appearing in class) but when i he did a appear and i talked to him he seemed. diffrent. As if the smiling, friendly, person from before had vanished and had turned into someone who couldn't hear a word i said. Then again i gave him the benifit of doubt because maybe he was just shy and didn't know how to talk. But, when i got home the next day after not talking to him so he wouldn't feel bothered he unfollowed me? I told myself i'd never get upset over something like that and even now i still think it's stupid. Yet, i still cried. idk we've only known eachother for a week so i kinda brushed it off the next day. Then it got weirder thought cause he kept staring at me when he thought i wasn't looking. At least it really really seemed that way. I kept my distance not speaking to someone who doesn't want my presence. Still, he rereads our messages (fyi if you read yoru ex's messages on insta they can see it update) and just staring at me. I don't know if it's cause he hates me or not. i just need someone (even though all my friends say he doens't) to give me more incite on why? a guy's pov maybe?
