Long story short I had a long distance girl I was dating staying at my place, she has family in my city also. We live about 2.5 hours apart

Everytime she comes here she always starts an argument and threatens to leave but whenever I go there it’s always cool. Toxic I know

So one night she was napping on my couch and my dog came up to her and kinda surprised her and her first reaction was to throw a punch at him.

Angrily I said “did you just f’n hit my dog” and she gets up and started yelling at the top of her lungs and packing her stuff. So I told her to go to her cousin house(because she was already packing and have a history of threatening to leave) and called her evil for hitting me small French bulldog that’s not mean at all.

Now I’m blocked, I feel bad for telling her to leave but at the same time don’t hit my fragile dog
