I want to ask out this boy but I’m not sure


So the boy I like is in the same grade as me but I haven’t seen him all summer, I feel like he ignores me some time because where ever I text him saying hi, he never responds. It makes me feel like I’m annoying or something, like he cant even respond. I text him on snap chat so I can see if he reads it, and he does but he never responds. We were really good friends last year because we were in the class, it makes me wonder if I tried to talk to him to much or if I was just plain annoying. Do you guys think I should wait until school starts again so we can talk and rebuild our friend ship or do you think I should do it now or just never do it?
