NL50: 4bet with JJ, facing K high flop OOP

[doublec]

Villain is 25/19/3 over 60 hands. He'd been 3 betting me a number of times preflop. About 2 orbits ago I 4bet and he folded. He'd 3 bet at least once again since then, which I folded to.

I should have called preflop maybe given that I had no plan for what to do if he called the 4bet?
