Dog affecting our relationship.

Hi everyone, We adopted a Rescue dog from the south a year ago. She came very misbehaved but learned overtime. While she is a good dog, she’s very loud and well, rude. I’ve never had a female dog only males and she will only listen to my fiancé. (I have tried the tricks and treats for obedience and I’m not looking for advice for how to get her to listen to me because she won’t, trust me) Anyways, we only have about four months of pregnancy left until baby is here. We argue over the dog being loud, pacing, barking, waking me up at night probably daily. The dog has taken such a toll on our relationship that I regret adopting, I thought I was fit to be a dog parent but with all of the negatives I’m really not. And he loves the dog so much that If I made it a dealbreaker it would probably hurt our relationship immensely. At this point it feels like he’d choose the dog over me if it came down to it and we have a very good strong relationship, getting married in a month. But all I can do is worry about being home with the dog all day when I’m on my birth leave. I can’t be with her alone as she only listens to him. At times she will even growl at me and I’ve done nothing but good for her. How will I handle this dog with a new baby, when the dog doesn’t listen to me? Must I lock myself in a room like a prisoner? I’m extremely depressed over this. And there’s nothing to remedy than to rehome but that’s not even an option now. I’m not looking for judgement please just I really need help I’m losing my mind. Thank you so much.
