He would call to try to explain things to her and she would fly into a rage. And that rage would give her power, strength, the ability to do things she couldn’t under normal circumstances.

Rrraaaaarrrgggghhh!!

She would crush the phone in her hands, then destroy the bedroom, throwing the king-sized sleigh bed out the window.

But that wouldn’t be enough. She would have to find him. She would leap, crashing through the roof. Two bounds later, she would find him by the bridge.

He would have just gotten out of the car when she landed on it, causing it to crumple under her. He would try to escape across the bridge, even as she balled up the remains of his vehicle.

HULK SMASH !!!

He would have to dive into the river as she hurled his balled up car at him.

Granted, this was a worst-case scenario. But he thought about it and threw away Catwoman’s phone number, then called his girlfriend to tell her he missed her.
