I don't believe

Oppoent is THEDUTCHE4141
I got him at 19/17 and he's generally pretty nitty but really likes to follow up his aggression with more aggression.

BTN is loose and fishy, but folds most of his hands post-flop.

At first I was playing back at him, then he started playing back at and barreling me. I've folded to a couple multi-barrel lines from him. At this point, there is a fair amount of distrust between us.

The point is?
Your hand is pretty much face up and he SHOULD value bet any A here. But I do agree his range is an A or air.

If you showed willingness to call lite its a fold. If you been folding a lot, its an ok call.

If you don't bet the flop I think you pretty much have to call here especially when all the draws missed.

Basic play is that I would call. Double flushdraws missed and he did not bet the flop. if he has a weak ace there its really not much to say about it.

According to stove you are 47/53 vs the range I set up. I guess it is an odds based call.
I think a 19/17 would play a weak Ace just like this versus an aggro player like you, but I also think you can heavily discount Axs from his range too since a 19/17 is much more likely to call out of the BB w/ a SC or sml-med PP. What do his 3betting tendencies tell you about SC & small PPs during a very attractive squeeze opportunity such as this?
