What does it mean if he keeps calling me dude?

I was hanging out with a guy like just him and i for the first time and he kept talking and he would call me dude a lot but we were sitting on his porch and he was like sorry for calling you dude I never even use that word
So I was like I hadn't even noticed he seemed pretty happy with that answer

I thought I was friendzoned too but he kept calling me pretty and he would say something like that perfect you like all the same things I like I don't know
