Make the right call, but get rivered.

[Robbr25]

Ok, I(Robbr25 below) took my time, made the right call, but he hit his river.
He had a good amount of outs(10), so opinions, would you have called?
Was the bet on the flop enough? If I had bet more do you think he would have actually folded? (BTW I had given him most of the chips he had, lol I was not on tilt though. I truely thought I had the best hand. And did.)
