crush help!!!!

So I'm a junior and I have a huge crush on this senior. He's so cute but kind of shy. Everytime I snapchat him, we talk back and forth for awhile and then he leaves me on read and like normally our conversations are boring so i know he's not interested in me. The first week of school I went up to him and talked to him for a little and that went great but then later that night when I texted him, he was boring. I decided to give up but then the feelings I had for him wouldn't leave so I decided maybe I should try again and while I was in the process of trying again, I started to see him ALLLLLL THE TIME around the halls and we would ALWAYS make eye contact and they would be long stares and sometimes I would smile or wave and he would wave back but that's it. Well yesterday I was hanging out with my friend and she pursaded me to snapchat him again and see what it's like. He responded instantly and this time, out conversation wasn't boring at all. We were talking from around 5pm to 1am but then you will never guess what happened. He left me on read again and the next day, I see him around the halls but I don't make eye contact with him bc I look down or away from him. Idk what to do. Should I keep trying or try to get over him and find someone else? Sorry for the really long story and the typos
