nl10 2 pair on a bad river.......

[bigmac366]

villian was 45/15 and i havent noticed him do anything retarded. his flop bet was strong and perhaps i shouldve folded there, but when the turn came his weak bet led me to believe he was on a draw, plus it improved me to 2 pair, easy raise right? should i have raised more? should i call this river bet?
