Do we hate this? (50PL)

Basically, did I play this hand correctly (15th hand at the table so no real reads)? For an aggressive player I don't raise my draws as often as I might (though I *always* bet them) so I thought this might be a good spot. Was I wrong?

Bet 1/2 pot on river unless he's a complete cs. He could easily have a busted FD/str8D.

Bet hard enough on the turn that he might fold a draw or Tx, like almost pot.

I think the A is a bad card for you if he's on a flush draw. Pot limit players just don't fold draws for some reason and it's very likely he's drawing to the nut flush. Depending on the player I give up or bet the river.
