Explain The Alternate Ending Of The Lamb To The Slaughter

Lamb to the Slaughter “So there it is let’s break up. I can’t live with you anymore”, he said as he slammed the glass drink on the stool beside him. “I don't understand, how could you do this to me”, she quietly said. As soon as she said those words, he stood up from his chair and stormed into the bedroom. Mary turned around as though as if she wasn't hurt and head to the kitchen. She looked in the refrigerator for food and saw that there was nothing. Mary then decided to go to the grocery store to buy meat. She put on her clothes and went out to buy meat. The strong wind blew on her whole body and tears started boiling up in her eyes. The things Patrick said started going through her head going over precisely what he said. Tears
There was no one, so she decided to go to the police station to ask for help. When she got there, no one was there. On the front of the door was a big sign. “BIG NEWS,” it said in big letters.

Finally, Mary was near him and scared him asking why he would be here. Patrick got really mad and said “ I ALREADY TOLD YOU HOW MANY TIMES THAT WE ARE NOT TOGETHER ANYMORE. WE ALREADY BROKE UP”. Mary feeling super sad started bawling but on the corner of her eye, she saw Patrick smirk a bit. She wondered why but didn't say anything and a few seconds later she ran away. She ran as fast as she can but got tired soon since she was 6 months pregnant, and then she meets someone named Bill. “Bill? Why is he in a police outfit, too. I thought he had his day off? ”, she thought. But before her question could be answered, he said to her “Please go home now it is very dangerous.
