Why did he do this

Ok soo… A long time ago I like this boy he found out I liked him and never talked to me we grautated 8th grade and we are going 2 diffrent highschools well after we gratuated a couple of weeks later he txted me and it freaked me ut he told me he would never talk to me again. We have been talking and I think I might be having thse feelings 4 him again but I dont want to ruin are friendship but I miss him I havent seen him in awhile what do I do!?!?!
