Like, Don't Like, Don't Know

Question--I have been contemplating what Sifu said about feelings-- like, don't like, don't know. I noticed a facebook post from Alicia saying something about feelings aren't facts, and Sifu said they are optional. Honestly, this 'bothered' me, because I don't think I should just pretend like my feelings are unimportant or don't exist. So, I ended up looking up the definition of "feeling." I found several, and most of them related the word feeling with the sense of touch or some other physical sensation. Then I thought, well, maybe he means there are 3 kinds of judgments. Could you guys please help me understand this better?
