I'd have raised the flop. Had I played the flop like you, seems like the turn would be an excellent spot to raise UTG's lead. I think you are still in good shape and its time to give the other players the opportunity to make mistakes when facing 2 on the turn. Pots large now and this is your best spot to thin the crowd if possible/ face others with the opportunity to make the wrong decision. In the evenet you are behind it is an easy call of the 3...or 4 bet on the turn. Your hand has several potential outs if behind, which is not all that clear as your bets may actually go in as the best hand, and you have a player near all-in and with a higher than norm probability of not playing properly and another guy who has a history of trying to muscle you... the most you have to put in on the river is A BB for showdown.

I think you should have flexed your guns a little more here.
