The 1st thing you should learn is to muck A10os when you're in EP.
As played, you need to bet more on the flop like closer to 2/3 pot or pot, don't check the turn, you should bet the turn. I don't understand the turn check after hitting 2 pr here, if you bet the flop w/ only 1 pr, why check the turn after hitting 2 pr unless you were planing to c/r him?
He prob had something like QJ or KJ & you let him get there by the way you played the hand.
As a side note, please convert your hands for easier viewing & analysis. This is the one I use...http://www.stoxpoker.com/hand_history_converter/
