"Love 'em" is Zoey Deutch's answer to the question just previously asked by Glen Powell, "when your significant other texts your boss more than they text you." "Leave 'em" is the option Glen gives for it being unacceptable, and "love 'em" if it's acceptable. In this case, Zoey Deutch answers in the affirmative by saying "love 'em," and goes on to clarify that she doesn't mind if her significant other doesn't text her often.
