DP does not kiss me unless we're having sex. If I go to kiss him he pulls back and then acts as if he didn't realise I was trying to kiss him before giving me a quick peck to make up for it.
Last night we're lying in bed, its dark and I lean over him and go to kiss him and he jumps a mile, pushes me away and says "what you doing???"
I get pissed off and say "nothing, just trying to kiss my partner, how stupid of me" and he says "but you made me jump" 
I'm getting really sick of it to be honest, I know its only a little thing but it's bloody wierd.
