need opinion :/

so there's this guy that i once's dated 2 years back, but ended things very well and actually start talking and became best friends apparently.. a week ago he ask me a question which he said " will you give me 1 more chance", in my back of my head i would love to but national exam are coming so i played it of cool by asking him why.. and he said " i still love you",, well me being me my heart started to pound and was actually happy of course. the next day we met(we planed this bfr he confesses that he still love me), so everything went well nth much like 2 old friends just catching up.. and 2 days later, he stop texting me and actually ignorin (?) ghosted(?) me or something like that. he hasn't been texting me every since, and thn last night he posted in his private account that he would like to date a girl which do the same sport as him... that's an ouchie. i actually don't know what to do or what to feel because to me when someone actually said the word love it's a big deal to me. tell me if i'm over reacting or having high hopes or even over thinking of stuff cause i just wanna clear this thing outta my head man :))
