PSB the flop. For good measure do it again on the turn, if you must, but that's it. You will often get killed on a flop like this and its best to find out early. A call on the flop bet should arouse your suspicions fully. Try to get to the river cheaply is my usual strategy here if he calls flop.
fold the river, he's called big bets with something big . and note he's no longer passive.
