So because of his aggressiveness I ended up calling down but I am pretty confused about this hand.

What am I am supposed to get out of his donking pot on the flop? He can do this with a set or any other strong hand as he sees his hand and auto bets, he can do it with a medium strength hand -weak K- or he can do it as a bluff as the board is super super dry. IMO he can always do any of these things.

I am more inclined towards folding since I think I'm going to be faced very often with a shove on the turn and then I am going to be feeling like a mistake to fold. I mean if I call flop why would I fold turn?
I am beaten by 2/3 parts of his range (not as number of combos but as theoretical breakdown) so again more prone to a fold right now.
