Your logic doesn't really make sense for this board/action. This kind of thought process would make more sense if you checked back a flush draw flop and bet a flush turn card and he c/r you.

On this board/card if there's anything your line reps its EXACTLY Jx. Pot controlling flop and betting the turn trips. You have exactly what he thinks you have, and he's still betting into you on the river.

River looks like a fold, I doubt he's value towning himself with JTx and the FD even got there.
