JJ - Missed value bet?

[POKhER]

Villan: 36/13.3/1.41 Over 75hands.

Now i never used to 3bet JJ because well, i was a bit of a wuss... So in a effort to get PFR slightly up and as its for value i now do.

However its gets me into Sh*ty situations like this one. Now did i wimp out on a value bet? Or good "free showdown"?
