Guys, What do you think if a girl hugs you goodbye?

Well, we went to a party and when I was leaving, I said goodbye and I gave him a hug, I felt he didn't want me to leave, because he held me so tight. I'm not sure if he felt I like him or something. Is it ok for you when a friend (girl) hugs you?
