interesting pf discussion with aqo 3/6nl

[bgmula]

been taking a shot the last couple of days, here is a very tough and thin spot where I have not clue what the best thing to do is

3 handed, i raise aq to 18, bb rr to 54
what is the best option? note that villain has been playing very straightforward and seems ok

i called, probably bad idk, flop is 3109, with 2 clubs, i have the a of clubs he bets 84 into a 110? pot, the way i played the hand, do i fold now?

thanks,
bgmula
