Hey AANutz83,
Betting again on turn is mandatory, because the board is drawy and you need to protect your hand. So, bet/fold 2/3 of potsize on the turn.
As played, it depends on how aggro your opponent is, but I would lean more towards a call on the river because all the draws missed and he is likely trying to bluff you out with one.
