Does he like me back based on his behaviour at school?

So sorry in advance for the long text: Befofe summer break he alwayse used to make eye contact with me and always was near me at school, so in the break I decided to send him a snap request, the first tome I did he never answered it but then 2 weeks later I gave him another request again and this time he accepted it, but then immediately he unaded me. Now at school he always avoids me, and whenever I go by past him he always turns around si that his back is faced to me and he did that multiple times. Yesterday he was 200m away from me w his bros and I was kinda staring at him from afar, but u know from that distance someone can't really tell who and what u are looking at, but then he looked my way and then when I say immediately I literally mean it, for the rest of the break his back was faced to me. And in Wednesday When i came into the school corridor I went to the toilet and when I came out I saw that he had turned around and his back is facing to me AGAIN. Today we had art and he came to my class and we had a 1 sec eye contact but I looked away cause I am heartbroken from him. Then 40 mins later he came back again asking the teacher uf he could lend a pencil because they didn't have any and I think he just have looked in my direction but I don't know 100% So guys, what do u all think? Is there a possibility that he likes me back? Should I try and talk w him, and if yes how do I start.
