I would feel inclined to call down.

If button is a lag he could be 3-betting the turn with as little as a flush draw.

I think its more likely that you are up against a slow-played set from the flop, or 2 pair. Against 2 pair you still have up to 8 outs to improve to a better hand, so I think a turn call is justified.

I would also check/call the river, because its possible that your hand might be best if your opponents had overplayed something like Jx, and the pot would be quite big.
