I folded something I normally never do

[Laetus]

Villain is a decent TAG who plays something like 21/17 and I'm playing TAG. Villain almost timed out before pushing and to me it seems like he did everything to make his hand look very weak, i.e. he timed out and pushed instead of 4-betting smaller. It kinda smelled AA or KK and therefore I folded. At that moment I felt good about it, but afterwards I fell like "wtf don't thrust your feelings, you made a squeeze and he could be shoving with AQ or whatever... god damn get it in!". What do you think about it? Thrust your feelings or get it in wtf?
