Early in the film, Martha is drunk and on top of "Who's afraid of Virginia Woolf?" It is very clear she is the one who "wears the pants" in this situation, which is an early visual example of a woman being more physically dominant in a relationship.

Martha demands George to stop so everyone can go dancing, to which he replies "Whatever love wants. This is something that is repeated throughout the film, which is an early example of a more submissive husband in a relationship.

Towards the end of the film, George "decides" to kill their son, to which Martha replies "I will not let you decide these things." Their relationship dynamic stems from not having their son and Martha not having control over the situations she's in is what causes her to face reality by George's decision based on Martha having brought up their son.
