Is a guy surprised when you catch feelings?

So my crush full on did make out with me pretty intense the first night I met him. I asked him for a kiss but he went sort of in hard to kiss me. Now I did catch feelings but I feel like he didn't want me to. but how can a girl not when its a guy she likes! So why is he surprised or pulling away now that I like him? He is the one who kissed me so good?
