I would hesitate to place "blame" on anyone. the two involved in this situation are not meshing and quite different. I dont' see anything in what he did as being the one to blame for everything nor is it all on him.

On the flip side, pursuit of someone that has made it clear that they are not interested is bordering on harassment imo. If I was to ignore or reply in short to someone only to find they not only follow up with me again on fb or other social media, I would have blocked at that point. Following someone to ask them repeatedly "why" they were leaving even tot he point that you follow them outside shows that although the man may have issues with intimacy as you say, I believe that you have a boundary issue that you seem to cross a lot.

Not placing the blame on either person but I think that it's unfair to say either of the two people were to blame for the failure of this friendship.
