PF, you've been at the table, you should know what to raise. Hard to say if it should have been more.
Flop, you pretty much have to bet the pot to deny the flush odds. Likely to win the pot right here. He only calls with TT+, AT or 77 (if he would even play it pf), or chase the flush.
Now with the turn FD and AT have you beat and as you say, you only have JJ beat. You played it just right up to here, IMO.
Turn call was a crying call and you didn't even get to see his hand. You only have 4 outs to improve (2 Ts or 2 Qs). You get a B for discipline. Probably should have folded the turn, but at least you got away on the river.
