[Student Caine]

I am as weak-tight as they come and I do not drop this hand.

I would have led the turn, but given that you did not and he bet I would have Check-Raised him the pot. He could have QJ here, but there are way too many other hands that he does this with (two pair or sets, all of which you have beat) - and on the off chance that he does have QJ you have outs.
