I've liked this guy for about a year now, but I think I would want to move on from him! he blocked me on everything. He is also in all 3 of my classes, and sits by me, and we talk sometimes. I really want to move on from him, what do i do??

So - you like a guy that has blocked you out on all social media. Not a good sign. If you want to know for sure, start up a conversation with him. Read his body language to get clues so you will be able to tell if he likes you back. If he has blocked you on social media because you were being a pest and you make a move on him, then you are not reading his cues to you saying that he's not interested.
