Why would a guy hug a girl by squeezing her and hug her tightly?

Like after the hug I still felt his body on me, but he invited me over for dinner and when we where leaving his like let me hug you before you leave and man he hugged me by squeezing me and Hugging me so tight I wasn't expecting that bc when we hugged before couple times he never hugged me that tight why would he do that?
