I folded AA am I a huge nit?

[djshawk]

Villian is 35/9 and folds to steal about 75% with a flop aggression of 1.6. I'd not seen him do anything particularly out of line while sat.

When he donked the flop I had no idea what it meant, a 1/3-1/2 size bet and I'd raise it up but if I raise here I'm committed and I just don't know what he's doing it with. The board is really dry so he's not drawing, so I thought it's either a bluff with a low PP or it's a monster. Looking through his stats I decided he probably wouldn't be making a move but that I'd call a street anyway and see what he did on the turn. The T on the turn was a bad card because I'm now behind if he was just getting frisky with top pair. I though for a while and decided I was beat most of the time so folded.
