To be fair we're not folding once we hit the Q high flush as we've pretty much committed ourselves at this point. Looking back over the hand this one ended up being more of an in game read based on prior knowledge of the opponent and his tendencies.

This villain is very aggressive and has no fear in triple barreling if he feels it will work. Given the fact he has been 3 betting about 20% of his hands from the BB we can safely call with this pre. However we can still polarize his range to usually include high rundowns, double suited pair hands, double paired hands and also stuff like AKJ4 ds with the dangler.
Once the flop comes with a pair we can comfortably semi-float this flop even though we now know we were ahead. Once the turn brings a 2nd diamond we have picked up a FD to go with our two pair and only a small part of his range includes middish rundown type hands. Once we commit to seeing a river we are obviously commited to calling whatever bet he may put out as well, as there stands a good chance we have the best hand. This villain does what alot of folks do when they bluff on the river HU and that's go full pot. Even though I don't have a full pot bet left in my stack, most of the time he still bets something less than full pot for value unless he's bluffing.
As I said before this one may not have been as good as a player dependent read played into this more than I initially thought, but always good to discuss hands nonetheless.
