<human>: Can you give me the gist of the text in a nutshell?

Our mother has been dating this guy since April and none of us are too fond of him. He has a mouth like a trucker, is an avid hunter and just not exactly our cup of tea. We wanted to have a girls Christmas eve and would be happy for him to come in the morning for Christmas breakfast. She is refusing and not budging. She is making us out to seem like the villains as he will have to spend Christmas eve alone. We tried to compromise by opting to spend the eve with our oldest sister and then come over in the morning, but she is pulling the "how dare you" card. We don't exactly know where to go from here and we definitely don't want a Christmas ruined over this. But none of us are just that comfortable with spending the holiday with a stranger.
<bot>: Mom invites weirdo boyfriend to Christmas without asking any of my sisters, we're uncomfortable, she's not budging.
