I really don’t like my boyfriends dog and I’m not really sure what to do about it?

I’m sure I’ll get hate for this but whatever I guess. The dog is “usually” fine and at times even lays with me but I can’t go near my boyfriend or she tries to bite me. I know how to handle dogs and train dogs and in a safe and responsible way we tried to introduce my dogs and his dog (before she tried to bite me). She tried to attack both of them so I will not let her near my dogs and keep them separated when she’s around. He sometimes brings her to my house when he comes over if he’s staying for a few days. This past weekend I had my dogs in my spare bedroom where they have their beds etc so they are safe from her. She tried to attack the door and when my boyfriend grabbed her she even turned around and bit him! When she’s around we can’t even play around or anything because she’ll try to bite me. I was laying in bed and he laid next to me and she jumped up and tried to bite me and when he grabbed her she bit him. I have a lot of experience with dogs and I just don’t understand her. She doesn’t display protective behavior she displays possessive behavior over him and he has no control. Especially since she bites him. I love dogs but I will not put my dogs at risk because of her. Not only is her behavior bad but she destroys shit. I love my boyfriend very much and I don’t want to say our relationship will only move forward based on his dog but I don’t see how we will ever be able to move forward. We’ll never be able to live together or have children (she tried to bite a child that came near him) until the dog is gone. She’s only 5 so she has years of life left (hopefully) and I would never make him get rid of her. He loves her. So I don't know what to do at this point. Does anyone have any advice? I could really use it. Thanks!
