Critique My River Play

[TheJackyl]

Game: $100 PL
Hero: $130 or so
Villian: $120 or so

I don't have the Hand in front of me but it went like this,
Folded around to me 1 off the button, I pot it with A22J DS. Villain is in the BB and he calls

Pot: $7.50

Flop: 34J Rainbow << I hit top pair, nut low Draw and Bet pot, Villain Calls

Pot: $22.50

Turn: 34J8 <The 8 is a spade, giving me top pair, nut flush draw, and nut low. He checks, I fire out $10 (considered betting pot, but didnt want to scare him off. Villain calls.

Pot: $44.50

River 34J8T <No flush, and Villain checks again. I consider what he could have and fire out a Pot Sized Bet

*My thinking is he could be on 2 pair or a naked a2, or an a25 wrap, b/c he would have surely raised the turn with a set. I think that if he only has 2 pair, I can push him off, and if he has the a2 low, I got him 1/4ed.*

Villian thinks for almost the whole time bank and just calls. Villain shows A234 and quarters me.

If I was the Villian I would have reraised pot there, would that be a bad play?
Should I have just checked behind on the river?
