Preflop - I make it 6

Flop - Fold to his raise

your 3 bet has a cold-call behind you. this should raise a red flag that he has a hand. that being said, 77-JJ and maybe even QQ are in his range. i feel like this is a set everytime being an unknown. as a side note, bet more on the flop, like 13 at least. tough but a fold here.
