What does it mean a guy takes your hand but kind of won't let go?

I told this guy my hands were cold and he said let me see. So I did and he took my hand and kind of warmed it up but he didn't let go. So I kind of took my hand back. After that he figured out i was ticklish and kept on poking me plus everytime we see each other we give each other a hug. anyway what does it mean when a guy takes your hand but kind of won't let go?
