According to my research
-"act + an adverb" means "to behave in a particular way"
-"act + an adjective" means "to pretend to be something"
For example, "she is acting innocent/confident/dumb".
But I am not so sure.
What is the difference between "she is acting jealously" and "she is acting jealous"?
Does "she is acting jealously" mean "she is jealous" (Maybe, she really loves her boyfriend and she gets angry when she sees him going with another girl)?
Does "she is acting jealous" mean "she is pretending to be jealous" (maybe she wants her boyfriend to think she really loves him but she actually does not love him at all)?
