flopped top set and tons of action 3-6NL UB

[pologuy64]

Well to be honest this is the lowest limit i play. I play 3-6Nl up to 10-20nl. I am by far a winning player. The reason for this post is the fact that i knew i was not going to win the hand. If you know your not going to win the hand which i did why not fold? the 3 reasons and the fact that i knew no matter what i was not going to win i was wondering if i could factor that into a fold. not a bad beat post, no need to move down in limits, just wondering if its ok to go with gut feeling and fold the hand.
