10NL, nut flush on paired board

[toymach776]

Tell me how badly I donked up this one:

Full table just broke up. Villain is 20/0 over 100 hands. Im thinking that I should have taken a bet flop, bet turn line. Not sure what I was thinking here. Comments on all street welcome but Im particularly interested in river play.

I should have reevaluated here because villain is not doing this with lesser flush. I wish I would have looked at his stats before making this terrible river shove.
