Villain here is 16/10/1.6

pretty nitty overral but plays weird hands sometimes.. most notable hand in this spot i stacked off on j55 flop w. AJ when i didnt think there were barely any 5s in his range and he showed up with q5 lol

anyway on this hand. i just let him keep firing when donked into because i feel like if i raise he might only continue with sets. OTR i feel like its an easy fold and his hand actually looks more like a set there than Jx when he shoves. should i have raised at some point earlier in the hand??

I like the way you played it, I think the river is a fold. If the jack didn't pair I'd consider calling but since now we're not ahead of any of his value range I'd fold.
