When a guy shakes your hand and holds it and you ask him did he mean to hold it and he says no shaking hands is a formality?

I have talked to him before a yr ago and I noticed he shows signs of interest but he says no to this question at the beginning of talking to him he asked me what were my intentions when I never hung out with him to the point of liking him and him asking that question was confusing and now he does this and recently I told him I liked him but he says he likes me as a friend with all that happening
