How does he really feel?

Me and this guy met in January and instantly became friends. I was completely comfortable around him from the start and we ended up kissing. He backed out after that and said he wasn't ready for anything like that. Fast forward a few months, we're best friends and everyone around us thinks we're dating because we spend all our time together. Occasionally he starts flirting with me and then does a 180, apologising. He acts completely different with me compared to others, he recently started touching my hair and grabbing my hand so I don't "fall". He even suggested that we travel together in a years time. Now, he knows I've developed strong feelings for him and fell in love with him from the first time we met but I don't know what he wants. Could it be that he isn't ready for a relationship or is it just he doesn't want one with me?
