Live 1/2 NL, flopped two pair, villain push

[cjk73]

Villain loose and aggro preflop. Will call down small bets with 2nd pair etc but overall seems to play well postflop. Also appears to be image aware (made a comment here and there like "gotta change that now that you saw me", etc etc).

My image fairly tight.

10 players, Hero on button ($250), Villain BB ($300), others irrelevant.

Virtually everyone limps pre, Hero holding J[img]/images/graemlins/spade.gif[/img]7[img]/images/graemlins/heart.gif[/img]

Flop, 7 (or so) players, $14

Villain bets $10, 1 caller, folded to Hero who raises to $50, Villain reraises all in, caller folds,...hero?
