Yuck yuck yuck, horrible horrible, no raise preflop, I mean he called your raise, but I would have at least three bet those mugs(j's). Now after the flop the only thing to even worry about is a backdoor flush draw. I guess you could also have a straight draw, which wouldn't surprise me even though there was a raise preflop. Then the villian bets the turn, now by betting he is saying that he has the flush, which if someone else has hit it, he has just given them the chance for a raise, of which he would probably would call anyway. Now I don't blame him for not raising the river since there are 2 other potential callers sticking around, and there is 4 to the flush up, although I don't know if that call was the best either.
