50$ NL - 5max

I have villain on 45/8 after about 50 hands. He is rather passive,
but he isn't a station. Calls most pre and folds to most cbets.
Didn't see him stealing a single pot preflop.

I don't feel ahead of his PFR range so decided to just call pre - horrible?
As played what is my river line?
At the table i thought that bet/fold is the best option, but I am not sure of this.

Seat 2: aaa ($9.90 in chips)
Seat 3: Villain(CO) ($60.00 in chips)
Seat 5: bbb ($45.10 in chips)
Seat 8: Hero(SB) [ J[img]/images/graemlins/diamond.gif[/img],J[img]/images/graemlins/spade.gif[/img] ] ($74.45 in chips)
Seat 10: BB ($21.25 in chips)
ANTES/BLINDS
Hero posts blind ($0.25), BB posts blind ($0.50).

PRE-FLOP
aaa folds, Villain bets $1.50, bbb folds, Hero calls $1.25, BB folds.

I would re-raise pf to help define villain's hand, otherwise fine as played.
