OMG, I folded a set

[Duck Rabbit]

No particular reads on villain, but he is not ultra aggressive or super loose or anything. I checked the flop to induce a bluff on the turn or let him try to value bet something like AK. After I raise him big and he pushes in, i had him pegged for KK. I don't think he is bluffing in this spot and I don't think he would push this hard with AK or KQ. One leak in my game lately has been not trusting my reads. I felt pretty confident in my read, went with it, and I actually folded the hand relatively quickly for a set. Can anyone else fold this hand? or is this far too weak?\

(Can I still post 1/2 NL hands in SSNL??)
