Flush draw on paired board min C/R?

[Roadstar]

Villain is 50/30/2. Very loose and aggressive preflop meaning he will open limp call with any two but open raises a lot too. I think he is a bad LAG as opposed to a good one as he takes his junk hands too far postflop imo. He likes to make these min raises postflop with or without a hand. If you're not betting, hes not afraid to make sizeable bets with or without a hand (3/4-full PSBs).

I'm starting to isolate him when he limps before me. Onto the hand:

Flop - we call here yes? I'm really hoping he is minraising me with a flush draw in which case he could be stacked.

Turn and River - he really looks like hes no a draw or some super weak hand, do we take a stab on the river?

Thanks!
