fold a boat against LAG?

[Wynton]

I have villain here as 49/30 over 150 hands. He raises liberally pf, but isn't stupid.

UTG limps, villain raises from co. I 3-bet with TT on button. SB calls. BB folds, UTG folds. Villain calls.

Flop: K55. UTG checks, Villan bets, I raise. UTG folds, villain calls.

Turn: 5. Villain bets, I call.

River: A. Villain bets, I call.

Should I have folded the river or done anything else differently?
