What made you fold?

I think it was because I knew I really shouldn't be playing this hand, and all of a sudden I lost confidence to bet at it. But you hit part of my thinking on the head as well. My pot odds are good, I have TP, this guy could have anything. Hell, maybe he just paired his 82o.... I don't know, I think there's two things to think about for me here. If I'm not confident to bet/raise with it, maybe I shouldn't call, and maybe I should trust my reads more too. But then he probably had pocket rockets, isn't this the way that they get played these days: limp in, call the flop then start rasing the turn or is it just me that's seen that a lot lately
