2 tables tonight, 15 mins into the game I look down at

I am UTG+2, I limp in, button raises, blinds fold, I call. 2 players to the flop.


I check, opponent bets small, I call.
Wanting to take charge now because of the 2 flush draws, I bet out and opponent instantly goes A.I.
So, I am faced with the humoungus over-bet...
- possibly up against Q-Q, A-Q, A-x or maybe even K-K but would villain really risk his tourney life with those K's that early in hopes I don't have an A? Is he trying to get
me off of the flush draw? Why so big of a bet?
All of those scenarios and not a single one of them
specifically passed through my mind until the ride home. All I thought was, I have top set. I did actually "think" about it for 20 seconds or so but it wasn't "what could he have?", it was more of sick feeling of "am I willing to risk all my chips this early?". So, subconsciously, I must have known that I could be in trouble but I didn't think of how I could be in trouble. I called. Villain throws up

and a King of some flavour. Out kicked. Needed one of three 7's to win or one three Q's or three 5's to split.
Am I dealing with a case of hindsight is 20/20 or is it a tough but ultimately right fold? Suck it up and live to play another hand?
