Bella the dog

I hate to say that I am jealous of a dog, but the puppy I got for my boyfriend takes up all of his time. He says that she "needs" him, but so do I. I am agoraphobic and barely leave the house except for doctor's appointments and very few other necessary times. Sometimes I believe that he loves that dog more than he loves me. I say this because this dog is the first thing he has loved since he had an emotional affair on me about 3 years ago. I have forgiven him for it but it will be a long time before I will be able to forget about it. He says it will never happen again and I sort of believe him, but as I said before it will be a long time before I forget about it. I made it clear to him when he said he wanted a dog that the dog is his responsibility. I won't walk it or feed it or clean up after it. That is his responsibility. He also knows that I am allergic to dogs, but insisted that he wanted a dog and was not going to stop until he got one. So I found one for him, but I can't even get close to the dog because I am allergic to it.

What do I do now????????
