AITAH for telling my husband not to lick his fingers when he eats?

It's really embarrassing when he licks his fingertips while eating instead of using a napkin when we are eating with my friends. (He can do what he wants with his own friends.)

He tells me I am 'critical' 'over-bearing' and 'make him feel bad' but it's so nasty! And it's gotten really bad, he wasn't like this when we started dating. So reddit, AITAH?
