First of all your bf needs to step up and take ownership. It is his dog and your house.
Your bf should shut the door.
Your bf should place the dog on the floor. You bf should not let the dog stare you down. He is telling the dog this is acceptable behavior. He should not defer discipline / training to you.
You may need to get help with a professional dog trainer but first need to train your bf.
My suggestion is to isolate the dog to small area in the house. When you feed the dog make the dog come to you and just tell her good dog.
You don't need to make the dog submit - look away. She recognizes you are the woman of the house but she wants her man and is taking it out on your house.
Your bf should go the kennel and let the dog know barking is not acceptable. He should great you first and let the dog see it. He should let the dog out in a confined area and not let her have free reign until she calms down. If she does not calm down she goes back in the kennel. Right now she is getting what she want by being a bitch. And your bf is nothing but an enabler.
