i got scared on river...really scared

NL20 Caribbean Sun Poker
Texas Hold'em No Limit ($0.15/$0.25)


me ($11.25 in chips)

villain ($15.77 in chips)

villain posts big blind $0.25

I get dealt [Jc Jh]
UTG calls $0.25
I raise to $1.25
BB (villain) calls
UTG folds
----- FLOP ----- [Jd 5h 3s] Pot 2.50
villain bets $0.25
I call $0.25
(I don't want to give away my hand just yet, with a rainbow flop I felt safe...also try to induce a big bluff on the turn...btw...I did have the nuts at this point, but i'm always cautious to tiny/pathetic raises)

----- TURN ----- [Jd 5h 3s][6d]
villain bets $0.25
i raise to $2.75
villain calls $2.50

----- RIVER ----- [Jd 5h 3s 6d][2d]
villain thinks thinks thinks, then checks
i check
(a check raise seems appropriate here with a diamond and a straight draw completed, pushing here (my original plan) could prove to be disastrous)

villain shows [8h 8d]

Go ahead, give it to me.
