Ignoring me or just being a bit uncontactable

I have been very good friends with a guy for a few years and over the summer up until Christmas things started to look like they might be leadng somewhere. He isn't the most forward of people and neither am I so maybe we both missed the boat with each other, or maybe everything was misread and we were just close friends, nothing more.

I sent him a message before christmas saying "i should have kissed him" one night when things seemed especially intimate. I got no response.

I spoke to him at a party after lots of drink on my part and lots of drugs on his. he told me he never replied to my message because "we are such good friends he wasnt sure what to say".

Since Christmas ive seen him a couple of times and had a quick "im sorry about the fight we had" chat, to which he said he cant really recall much of what was said.
Hanging out in small groups since has been fine and i thought things were back on track. Even again at a party, things decended into old behaviours of falling asleep with our arms around each other, holding hands etc and generally feeling completely comfortable, behaviour which to me is either reserved for a very close friend or someone you are attracted to.

But when i text him during the week wondering if he is up for a drink or something i get no reponse, i have sent messages on maybe 3 seperate occasions now (and weeks apart so it isnt like i am pestering). Now yes he is a guy and yes he is really very very bad at keeping in touch with most people, guys/girls/friends/family alike. But i am beginning to take this all to heart.

Is it too much to hang out with just me, is he afraid i will get upset and emotional again.

Is he genuinely not replying because it slipped his mind or he lost his phone etc.

I thought things were back to how they used to be but i feel like maybe they aren't.

I know we need to talk about the whole situation and just establish where we stand, because besides the drunken semi argument, this has never been resolved and it feels like we cant move on until then. At least I can't given i can't stop thinking about this.

Some insight would be good, this guy was one of my best friends and it seems like now i am just being kicked to the curb which sucks.

it is funny that i am not even attracted to him anymore now i purged myself of that, but i miss having a friend who is there and who can make me feel special and safe, so i miss that aspect of our closeness a great deal and am really at a loss for how to rectify it again
