It sounds more like he is uncertain that he wants to be more than friends. Maybe you should think about why you started to date and move away from being friends. It can be hard being friends with the opposite sex sometimes the harry met Sally syndrome comes in and you both move into a relationship that is perhaps not right for you.

I mrean ok he could have hang ups about physical contact I will agree about that but to me it sounds like he is not certain about this relationship if he is still developing feelings of affection, after a year you should be further on than this.

Maybe this relationship is just not right and you should have stayed as friends.
