Combo draw on a weird flop, am I too bluff-suspicious?

[friend_]

Villain is 24/15/3.53
CO is a semi-loose guy with calling station tendencies -
28/19/1.53.

BB checks, <font color="#CC3333">Hero bets $80</font>, CO calls $80, <font color="#CC3333">BB raises to $360</font>, Hero ??

If is was HU I wont fold ever, but the guy behind me stopped me from shoving.
Anyway I am not really shure about my fold, cause the only real hand villain may have here is trips, this flop is also wont probably hit anyone of us, so it is very good to make such moves with FDs and air.
