This guy that I'm attracted to kept looking at me and hanging around, but he wouldn't really talk to me. At one point he did touch my hair and told me if was soft, and he hugged me goodbye. Is he interested?

He won't talk to you but he touches your hair and tells you it's soft and hugged you?  Kind of creepy, don't you think?

Sometimes people who are not used to communicating in social settings do awkward things, but they don't mean to .

He's trying to communicate with you best he can that he likes you but he is shy.

If you're interested, a good person can always bring a nice guy out of his shell. Just start talking to him to make him feel more at ease and not feel so awkward.

He just doesn't know what to do or say right now and believe me at home he is trying to figure this out too. It's not easy for some people but yes he likes you.

It seems that he is interested.
