Live 3/6 top pair/ flush draw gets 3-bet

[OvrTheTop111]

Live 3/6 game. Im playing in the loose passive game that every player dreams about and I am killing it. There are several limpers every hand, noone folds top pair, and you're paid off when you hit. This table is so good that I had only intended to play for a couple hours, but 5 hrs in I'm stiil playing when this hand comes up.

Villian is new to the table, but from her demeaner at the table I can tell she has spent a lot of time in the card room.

Hero is UTG with Q [img]/images/graemlins/heart.gif[/img] J [img]/images/graemlins/heart.gif[/img] and limps.
Utg+1, MP1, CO and Villian on button limp. SB folds. BB checks.

I limped because I wanted to play against a lot of people and for several hours an UTG limper usually resulted in multiple limpers.
