NL100 - Am I thinking too much here? Standard fold?

[K䲰䮥n]

Villain is 17/9, a reg at my stakes. He like NEVER folds to MY 3bets. So far I've 3bet him quite often this session so he might think we're "at war". So far he has folded to my cbets in 3bet pots. Is he betting because he know that im a badass that wins monies? IS he is he?!?!

Effective stacks 100xBBs, NL100 6max.
5 handed.
