should i give her space or move on?

[Roberto]

I had a crush on this girl and we have been friends for awhile until one day she suddenly blocked me on social media and when i told my friend he said she was not interested and i didnt tell her i liked which could of been one of my friends but when i went after school talk about it as soon as i was going to bring up the question i called her name first and right after that she gives me a nervous smile then says hi and walks a bit away and i was very dissapointed that she avoided my question because i'm still confused why she went from talking to me to blocking me should i just let it go and be clueless of what really happened or give her time to think my close lead is someone could of told her i liked her and she probably got very scared or disinterested and blocked me but still thats not cool but is she avoiding me or give her time to think it
