Why won't he answer my messages?

[Pink Kitty 2]

I messaged my old crush 5 times and i decided to send him a 6th one and he has not replied. I feel something needs to be done. I haven't talked to him for 8 months or seen him there is no other way for me to contact him. I'm not sure if he remembers me. He has not replied or accepted my friend request it's just sitting there no matter how many times i resend it or send another message. The funny thing i can't get my mind around is he hasn't blocked me. I have sent him 6 messages in 5 weeks later I'll send him another one and there's nothing so that would be my 7th. I just don't know what to do I've moved on he is always in the back of my mind. I'v even kept myself busy. The thing that's annoying me is he hasn't blocked me but he went online to change his profile picture. Please don't say he is not interested because he hasn't blocked me and it's been months since i spoke to him. Any other advice on how i could contact him would be a great help to me. I want to tell him I've become more confident than I was before, do you think if I try sending him messages everyday would seem weird? Something's telling me he's ignoring me because he might be shy to talk to me, i'v even waited 7 weeks and had nothing .. I mean he could at least reply 6 is enough unless I send them everyday? Any ideas? I just don't know I've had other crushes inbetween the 9 months but i just always want him. I also tried messaging one of his friends but his friend seen the message but never also replied. Do I try another friend? I'v even tried phoning the college but i messed up my words (long story)
