This wasn't always Hera's reaction, however. On one occasion she decided to give Zeus a "taste of his own medicine" by conceiving and delivering a child by herself, proving that she really didn't need him anyway.
It didn't work out quite as she'd hoped. She gave birth, as the sole parent, to Hephaestus (God of the Forge) who was born with a deformity that made him lame. Zeus was not impressed, and Hera rejected her son, sending him away from Mount Olympus to grow up among the mortals.
At other times, in reaction to his continuing infidelities, the goddess Hera simply withdrew from Zeus and the other Olympian gods and goddesses and wandered around the earth, often in darkness, always eventually ending up back at the home where she'd spend her happy youth.
In spite of how he had mistreated her, Zeus did love Hera and, more than that, felt as if part of himself was missing when she was not there for him.
Once, panicked that Hera didn't seem to be in any hurry to return this time, he invited her to a "mock" marriage ceremony that he'd arranged to a princess near her home.
She couldn't help but be amused to discover him making his vows, not to a princess, but a statue! Hera's laughter broke the ice, and she forgave him and returned to Mount Olympus to resume her role as wife and queen.
