Call or fold?

[EasyPoker]

I like your 4bet sizing here.

Because?

Folding is really bad though, consider his range and your equity vs it.

Because? Not saying I disagree with either, but that type of response doesn't help other members of the forum learn AT ALL.

never folding vs a 50/42 here.

This, simply because his 3betting range is as wide as a whore's gape, and your 4bet likely just pissed him off so that he jammed. This defo happens at lolstakes.
