Is NOBODY wrong in the post ? POST : So, to start off, my fiance has a Chihuahua, which I hate small dogs in the first place because of bad experiences with my Grandma's dogs. However this dog of his is especially bad in my opinion.  
Fiance has had this dog ever since he was 12. He's very attached to Dog, obviously. Dog has been sleeping in his bed that whole time. Fast forward to now. My fiance and I are planning on moving in together soon, however we have a huge dilemma. The dog.  
The biggest problem is that this dog is highly aggressive. Although he's come to tolerate me, I still feel the place where he bit me on the face a few months ago. I didn't even approach the dog when it happened- my fiance was saying "Isn't he cute?" And shoved the dog in my face. It surprised both me and the dog, and the dog reacted with a bite. Obviously in a fit of anger due to the pain and the mark it left, I mentioned to my fiance that normally when dogs bite they're put down, causing my fiance to burst into tears.   
I also feel like my fiance gives more affection to the dog than me. I know this isn't true, but it's honestly what it feels like. I told him I am *not* ok with the dog sleeping in our bed when I move in with him. The only reason I tolerated it when I was visiting him was because I was the guest and I've been taught a guest should be thankful they're being allowed over at all. He's upset with me and is begging for me to accept the dog in our bed.   


The truth is deep down, I'm more mad at him than I am at the dog. All he does when Dog is involved is try to get me to coo over it. I'm honestly sick of it, and I know it's not the dog's fault. Whenever I try to talk to him about it he gets really upset. I don't *think* I'm being too harsh, but at this point I don't know.   
What do you guys think? Am I the asshole?
