If he's bluffing a couple of diamonds, that's about a 1 in 17 or 6 in 100 shot, that could inflate your 12 in 1,000 to about a 72 in 1,000. Against the 120 in 1,000 you lose... still bad. Not to mention the times you get 3-bet in those 120 times.

That said, raising is a large part of nature in your spot. Throw out your bad play before. In the moment, with A2 or AK, I'd raise against a douchebag like this unless I really thought it out.

EDIT: I'm a dumb-fuck. You're gettin' like 26:1, I'm guessing? Your raise is +EV.
