Reraise this river? A boat from the blind

[DrPublo]

PP 200NL 6max, 4 handed. Villain in this hand is the SB and aggressive, to say the least. He's c/r me on the turn twice in the past 20 mins. One I laid down AQ on a QJx flop and the other time I mucked middle pair and the nut flush draw (should have checked behind but this is a different story).

Hero has $200 or so, villain covers.

Hero is BB with 5 [img]/images/graemlins/spade.gif[/img]2 [img]/images/graemlins/club.gif[/img]. Folded to the villain who completes, I check.

Flop ($4): 6 [img]/images/graemlins/club.gif[/img]2 [img]/images/graemlins/diamond.gif[/img]5 [img]/images/graemlins/heart.gif[/img]

Villain bets $2, Hero raises to $7, villain calls.

Turn ($18): [6 [img]/images/graemlins/club.gif[/img]2 [img]/images/graemlins/diamond.gif[/img]5 [img]/images/graemlins/heart.gif[/img]] 5 [img]/images/graemlins/diamond.gif[/img]

Villain checks, Hero bets $12, villain calls.

Villain checks, Hero bets $30, Villain raises to $60, Hero...?

Thanks for the input. All comments welcome of course.
