bad fold?

[Caliman]

My first post here so bear with me

1/2 NL online, no reads on villian
folded around to hero in MP2 with KK, raise to $10 (too small?), villian calls in the SB, 2 to the flop both w/$190 or so.
Flop is J J 4 rainbow, villian checks, hero bets $15, villian min raises to $30, hero calls (come back over the top here?)
Turn was a blank 6 and villian bet out $45, after some consideration I folded believing he had AJ, KJ, or maybe TJs
Did I play it too weak/tight from the start, tough to tell with no reads if I made a good laydown.
