I am really unsure here as this hand happened weirdly, but I will attempt it anyway. Normally this line indicates one where you can comfortably fold. However, villain could have easily been floating you with AQ, AJ, maybe even AT, thinking you did not hit that ragged flop. I would probably shove here and take a note on villain to be honest.
