Is folding here too nitty?

PokerDruid

Background:
This player and I were going back and forth and whenever I checked he would bet.

5NL (6 max) - Holdem - 6 players

Hero (SB): $6.19
Villian (UTG): $5.33 (VPIP 33/PFR 21/3B 8/F3B 25 / Fold to C bet 75 / Hands 162)

Pre Flop: (pot: $0.07) Hero has Ah Jh
UTG raises to $0.14, fold, fold, fold, Hero raises to $0.60, fold, UTG calls $0.46

Flop : ($1.25, 2 players) 9h As Qc
Hero bets $0.59, UTG calls $0.59

Turn : ($2.43, 2 players) Ks
Hero checks, UTG bets $2.43, fold

UTG wins $2.31

Comments:
I was pretty confused when he bet full pot on the turn only leaving himself with $1.71. I don't see how I could be ahead in this situation though. He could easily have QQ, AQ, AK, JT, or even 99. Knowing this player he would have 4-bet with AA and KK. Is it too nitty to fold here?

I think the default here is: don't pay off big bets on the turn or river. Given the prior action it's hard to find any draws V might semi-bluff like this, so finding hands you're beating is so challenging the likely conclusion is you're beat.
