Why would a guy do this?

I got out of a abusive relationship I was hanging out with one of my guy friends yesterday we sat on the park he asked if I was okay I broke down crying saying I wasn’t and he asked if I wanted a hug I said yeah and he hugged me right and put his head slightly down because I’m short I’m 5’1 he’s 6’2 he comforted me and told me everything is gonna be okay and out of nowhere he carried me like bridal style and sat me down on his lap kinda and put his hand around my waist and comforted me saying everything is gonna be fine and gave me advice was he just trying to be nice or is he interested?
