do you push this flop? (J/J)

[aaron7484]

PokerRoom.com, NLHE, .15/.25 blinds, 7 Handed.

Hero: $15.80
Button: $14.90

I had no read on the villain.

PREFLOP:
Hero (UTG) with J/J raises to $1, 3 folds, button raises to $3, 2 folds, Hero raises to $7, button calls. (POT: $14.40)

<font color="blue">My thought at the time was that by making such a small reraise I was not committed to the pot if he pushed. If he didn't push, I would on the flop.</font>

FLOP: 5/7/K (rainbow)

What do you think?
