My guy friend did this, what does it mean?

We went to the mall one day.
Me and my friend had to leave the mall early and we said our goodbyes, I went in for a hug (I was expecting chest to chest) - he hugged me sideways. He's has a huge crush on me since the 2nd grade, what does this sideway hug mean?
