Playing a funny 3 blind game, BU puts in 0.5bb, SB and BB put in one BB each, action plays out as usual from UTG to BB but limping in is for 2BB, doesn't matter too much for my hand though.
Villain flats quite a lot pre, but is very tight and very aggressive so far post flop. I've only played about 20 hands so far and she always had he nuts when she bet/raised.
Me (MP) 130bb
Villain (Blind) 500bb

6 6 villain puts me all in for about pot size.
Can I fold here? I think I beat KK, QQ, and flopped 2 pair without a 6 (J xnot too likely tho I think) in her range but is crushed by her sets or maybe even 6 x now.
