My fiancé just pulled a gun on my dog, what should I do?

I am extremely disturbed and feel I need to leave him after this. My dog and him got along well in the beginning. Then my fiancé began being mean to my dog. Lately things have intensified between them. Ever since we visited my fiancés family, my dog has began attacking my fiancé anytime he comes near him. I thought my dog was just overwhelmed from being in a different environment around new people. However, they clearly hate each other now. My fiancé tried to kiss my dog and he bit his ear. Then he pulled a gun on my 10 lb dog. I don’t know what to do. I don’t know why my dog has only been attacking him recently. I don’t know what to do about it. However, pulling a gun on my dog is completely unacceptable. My dog is everything to me and he knows this. I am afraid and don’t know what to do about this.
