Lovers, No More

In the late 1930's there was a married couple that lived in the harsh north Minnesota wilderness. They have lived there for over thirty years and the deep love they have for each other had now faded into a mutual dislike for one another. Everyday they bicker over anything and everything, until one day the women snaps and she storms off into the woods. Her husband followers her, but loses her track quickly with the blizzard brewing. In the woods they find a mysterious creature that will make them tear each other apart, literally.
This is a horror story some friends and I made up during English. I just expanded on it.
