use your own intuition when it comes to how a guy feels about you. There is no known fact or writings on the subject when it comes to human bonding. Everyone is different in there reactions and motives
That's another sign
If he says he don't like you and still shows the other signs then he likes you a little bit
He likes you but he doesn't want to show it because he is not sure about your feelings for him so he thinks if he tells you his feelings he will ruin the friendship because you don't feel the same.
He likes you, why is he trying so hard to hide it?? it's confusing.
He doesn't want you to know.
